Note by WebPM: I have split this off from the photography thread partly to make this discussion more accessible to others who have questions, and partly to keep the other thread on topic.)
...Finally, this is to WebPM. I may Post again, though. But after 3, 4 attempts to find WebPMs Post, I could not, and then I recall a thing said by MrRobert123, in that Replies Change depending upon how a Thread is entered, and so I clicked upon the Thread TITLE, instead of any reply (from the HOME Screen... and now I finally see your Reply, Mr.WebPM.
(I wanted to keep this Thread about Pictures, but then that happens, and so I Post it here, as it happened, rather than my previous Thread. Excuse Me.)
EDIT - From DC: This Post now does not entirely make sense, when used as a Starting Post or as an Introduction. To anyone reading, Please ignore the sentence here which says that this Thread is "about pictures", for THIS Thread is not about pictures at all..!! Most of all, Please see the first *Real* Post from myself, below. I myself can only wait to see what other people (including NAS) do regarding this Thread...
This time, it is WebPMs message (and 2 others) which is missing. From the same day, entered NOT via the Title. (Monday Tomorrow, Hope you are well, WebPM.)
These are really helpful, thank you. I'm sorry for the trouble you've had to go to in order to paste these, but they make things so much clearer, so I appreciate your help. Since the pattern appears to be consistent, I think I have enough screen shots.
I can see what's happening, and I think I understand the reasons. I'm not sure either whether it's intended to work that way, or whether, if it is, that's a good idea, so it's going to take me some time to investigate. I'll try to have an answer in a couple of weeks; I'm not sure, especially with the holiday coming, whether I can do better than that.
The difference is, as I think Disallowed Cynosure has suggested, between a view that is centred on a message, and a view of the whole thread. This forum,as we know, takes a "nesting" approach, that takes account of the fact that I am replying to a message from DC, and shows that by indenting my message under DC's. By contrast, in a "linear" forum, my message would always be last, even if DC's were ten messages higher in the thread.
So, if you follow a link to my message in this thread, the software is mostly concerned to show my message in context with DC's, and also any replies to my message in particular. For that reason, it does not show any other replies to DC's message. If I scroll down a bit and use Load Next, those other replies appear, but below the messages that are already showing. These Load Next links are just out of shot in most of the screen images above.
If you follow a link to the whole thread, then all replies are shown in their places (although you may have to use Load Next or Load Previous to display them). As a result, if you've started with a link to a message, the "missing" messages under discussion in this thread may, when revealed, appear somewhat lower down in the thread than if you started with a link to the thread.
Links to messages appear in email notifications, and also in the forum in "In reply to" links above messages. Links to the thread appear in listings of the topics in a particular forum, and of course the list of topics on the forum home page.
As I said, I am not sure that listing the same messages in different orders in different circumstances is helpful. I will need to look into this before commenting much further, including speaking to the software suppliers.
I am sorry to DC for causing offence by moving this topic into a separate thread. It has been helpful to me to be able to see this topic in isolation from others, and has made it easier to understand. My apologies if that was not true for others. I'll try to find better ways of starting a new thread if I do need to move messages, but I was conscious that starting a split thread with a message of my own would complicate the nesting and ordering.
I have mentioned before that, in my view, neither nested nor linear forums cope well when many themes are discussed together in one thread. We've seen what happens in a nested forum such as this. In a linear forum, contributors tend to quote massively from the messages to which they are replying, because several essentially-unrelated messages are interspersed, and the whole string becomes huge and hard to read.
To WebPM: Thank You in return, you are so very honest, and of course, Thanks Much for all that you do here. My own Point-Of-View is that I would usually say "どういたしまして"... yet I AM glad to have helped someone important with something important and to have a genuine appreciation stated about my doing so...! :-O & :-D
Yet you say that you "have enough screen shots", and so I am now wondering if that is the end of this Thread, or something...? (It shall thence disappear underneath the great tide of "I have a child" Temporary Posters...)
I should add that, perhaps apart from the last Picture, I made certain to press *all* "Load Next/Previous" Options, before Posting the Pictures. And again I say that it does not seem to make a difference if I am Logged In or not. Another person doing the same may have different results...?
With regards to causing "offence", it is as I said: I did not expect it, yet this was made worse by my not being correctly able to find it... It was the idea that I created it when I actually did not, that threw me... yet that is all grist to the mill for myself (i.e. experience).
If you reply to this Post, then please do so separately from the next, for it addresses a different matter which is not a problem to myself yet may help some others. Good Fortune to Yourself, as always. :-)
I wasn't intending to bring an end to the thread. As I mentioned, I will be raising this with the software suppliers. I have started by talking to our support specialists, in case anything we have done has affected this. By all means post asking for updates, or with anything new - I just didn't want anyone to go to the trouble of posting more screen shots if they just show the same thing.
It's rather encouraging though that this thread disappears quickly, as those other threads are people seeking, and finding, help and encouragement, which is the purpose of running this forum.
When I checked some of your examples, I found that all the messages were there. However, as I described, if you've followed a link to a message, the messaging order is different from what it is if you followed a link to the thread as a whole.
It sounds as though you're not finding that. I can only suggest that we work through the same example using the two links. As you know, a link to a thread looks like this:
i.e. it ends with the thread name, whereas a link to a specific message looks like this:
i.e. it ends with the message number twice, separated by hash characters.
Next time you have a problem, could you post both links here? Sorry for the continued trouble.
(NB I've posted this twice, in trying to make sure that it was being threaded properly. Sorry for any confusion.)
This is a direct reply (apparently) to Mr WebPM.
Your reply, Sir, now dates from "Two Months Ago".
Please tell us how this business is getting on. Replies do still disappear, yet few Threads are long enough to cause that, of late, and so less persons notice... but the trouble is still there. Thank You Very Much for your Time.
I'm chasing this up. However, I still believe that this is about threads being displayed with messages in different orders, as I set out in my previous (lengthy) response. I've seen your suggestion that I can see messages because I'm using an administrator account, but I don't believe that that is the difference.
I can see why the order varies (and I explained that too). However, I can also see why that's confusing.
I remain of the view that no system is perfect, and in particular that no forum system copes well with threads that get very long and complex, and cover several different issues. To that extent, I see your point that threads are tending to be shorter as a good thing.
I said that I thought that I had enough examples to allow me to understand the issue. Nonetheless, do please post more screenshots, ideally with the links as well, if you still see it happening. Do please check, though, as I suggested, that the missing messages are not displayed further down the thread, and visible if you Load Next or Load Previous.
I can't speak for DC, but I thought earlier today that one of my messages must have been deleted by a moderator (I could potentially see why because of 'triggering' content, but would have expected a direct message or something). It was however, as you describe to do with the order in which the messages had been originally posted. If I link to one post  by NAS15974 (warning: suicide references), my reply doesn't show up even though it's a direct response, because other replies to a higher level had been posted in the interim. You have to click 'Load Next' twice for it to show up. If you follow the link directly to my reply (also possibly in bad taste), it appears underneath what it's a reply to without the intervening higher-level posts, which have disappeared.
If someone deletes a comment, do all the replies to that comment, and replies to those replies, also get deleted?
Thank you for the example. I don't think those messages are in bad taste; they are real and personal. If anything, I feel awkward about using them for this purpose. I hope it's right that I do, and helps with the mutual support that is being provided.
It has now allowed me to work things out, so hopefully that's a good thing.
I would suggest that the "standard" message order is best seen by linking to the thread itself. On that basis, the "waiting is killing me" comment to which you replied was followed by a short side-conversation between BlueRay and Robert123, then an exchange between yourself and NAS15974, with a further response from California to BlueRay interspersed, and finally (at the time of writing) NAS15974 responds to a higher-level comment from the moderator.
The link to your reply that you provided shows, as you said, your message immediately below its "parent", the "waiting is killing me" comment. California's response to BlueRay shows, but not BlueRay's message itself. There's a link of course "in reply to BlueRay" that loads a version of the thread centred on BlueRay's message (i.e. it's a link directly to that message, instead of to yours).
So, it's true that those views can omit messages, and my apologies for taking so long to see it, and for anyone who was frustrated by this (DC in particular, I feel). It's quite hard to work out. What I need to do is to get some rules from the suppliers on how they do these things.
I can see the intention, so I think it's a design decision, rather than a bug. If you follow a link to the message, that message is shown in context - i.e. with its "parent", so that it's easy to see to what the message author was replying, and hence you can understand the response more easily. Two links to two different messages in the same thread will therefore produce differing views of the thread (which is what you found). If you want to review the whole thread and see everything in context, try a link to the thread.
And yes, I believe that, if a comment is deleted, replies would also be deleted, because they would have lost their places in the thread. Thinking about the content, they would also be replies to something that the previous author no longer wished to say in public. In some cases, if I said something and then regretted it, anything that someone said in response might just make things worse, and be best removed?
OK, here's an odd one: http://community.autism.org.uk/f/adults-on-the-autistic-spectrum/12572/trying-to-get-support/ lists '7 replies', and at the moment none of them are showing up for me.
Please try it now. This was an HTML issue, and looks like something of a one-off. However, we are working with our suppliers to try to prevent any repetition.
Working now. I wondered if it might be why some other comments weren't showing.
