Can we either make this forum's smileys more expressive, or at least improve the descriptions? Maybe the admin wanted the descriptions to merely describe the icon. But wouldn't it be more valuable to explain which emotion the icon conveys? 
01 -- "cool": Guess this icon makes sense.
02 -- "cry": This icon is clear. What about describing it as "sad"?
03 -- "embarrassed": Did the icon fall asleep with a cig and set itself on fire…? Shouldn't the eyes be half-closed to the side or downwards for embarrassment?
04 -- "foot in mouth": Description is quite cryptic. What about "shocked"? 
05 -- "frown": This icon looks rather "worried". #16 is totally more frowning than #05.
06 -- "innocent": This one is clear.
07 -- "kiss": Guess the icon is clear. What about "affectionate", "loving"?
08 -- "laughing": The one is clear. Maybe describe it as "cheerful?"
09 -- "money mouth": How many people want to convey they feel like an Incredibly Cheerful Hulk? Why money? Why green? US dollars? Why mouth? I don't get it? Can we replace this by something meaningful?
10 -- "sealed": As in "my mouth is sealed", "no comment"…? What about "sighing" or "frustrated"?
11 -- "smile": This icon is clear. Maybe describe it as "happy"?
12 -- "surprised": This icon looks like "yawning" / "tired" / "disinterested" to me. Can't put my finger on what is missing for "surprised".
13 -- "tongue out": Description is slightly redundant. What about "cheeky", "teasing"? 
14 -- "undecided": This icon says to me "Eeeew… I'm supposed to eat WHAT?!?!?" Can the undecidedness be made to look more neutral/questioning, and less disgusted?
15 -- "wink": This is the most unwinking smiley I have ever seen, LOL… Why are the eyes just two pixels? Please make it more visibly wink. What about describing it as "just kidding"?
16 -- "yell": Why is this "yell" when the mouth is closed? What about "annoyed", "angry", "mad"…?
I know this is subjective, but I don't want to be conflicted about using a smiley that is labelled with something different than what I think it means. If others disagree, I'll go with what the majority says.
PS: And why does the window say "Use left and right arrows to navigate." Does that only work in certain browsers? It doesn't navigate anything for me.
