The smilies/emoticons haven't worked in a long time, but I was finally able to fix some of them. You should be able to see and use (by clicking on) the available ones on the emoticon menu in the right-hand column when you make a post. Unfortunately, the fix doesn't seem to work on animated emoticons and even some of the popular stationary ones. I'll try to find a better solution, but at least you can use a smile, frown, wink, grin, and several other basics.
