This would be a very good sticky thread on a regular forum. It can also quickly help new member navigate the forum and change their NASXXXXXX ID to something more recognisable. Thanks for making this thread. I do hope that NAS will put some useful threads like this in a sticky or pinned threads place for people to find.
