Why aren't smilies on?
They are the devil's tool. In fact, I suspect that you are in league with Satan for even questioning such an obvious fact.
Seriously though, we all hate 'em, and the times we need to use them for effect, we can just host them ourselves. They'd probably have to all be changed to look half-decent on these boards anyway. :P
Edit: And maybe so MonCaptain, but I like the good ol' fashioned :P, without any graphical crap. At the least, that graphic must /not/ be forced on us.
