The smileys here are kind of weak. Now, I'd love it if they had onionhead smileys.
Smileys

I would be all for a 'Like a Beer' button.
No, that is not the best suggestion I could come up with. Here is a better one - Take the caps lock key off your keyboard. 
It sure would be nice to have smileys in chat.
And one smiley I would like to see is one that looks like Darth Vader so I can use it when I feel I am about to crush my opponent.
But, other than my desire to have this nifty little icon, I think smileys will make it easier to joke with opponents.
