I think the default emoticons ( B-) for example) should be changed into Moos or something.
Also, maybe you could add all the Klonoa Heroes faces? lol
But don't have them as ": O" faces 'cause seeing them used a bit too much in one post looks a little awkward... I think the Klonoa ones we have now should be renamed to :klonoa(emotion):...
For example X_X would be :klonoax:,
would be :klonoathumb:, and so on.
