Yes, discussing in the wiki may not be as fun as discussing in the forum... one reason probably because there's no graphical smilies in there.

So, I've uploaded some smilies. The following is a list of the smilies I've uploaded and the wikitag you must use in your editing to show the smilies:

smile.gif [[Image:smile.gif]]
biggrin.gif [[Image:biggrin.gif]]
wink.gif [[Image:wink.gif]]
laugh.gif [[Image:laugh.gif]]
tongue.gif [[Image:tongue.gif]]

There. I hope the 5 smilies above can represent the basic human emotions wink.gif at least for now biggrin.gif
