QHAllAround - there is a known issue with Safari on Mac OSX and the smileys. This is a limitation of the software, and hopefully it will be something that the software maker will fix in a future release. For now, if you want to do smileys in a post, you can try using Firefox for Mac or IE for Mac and see if the smileys show up. I'll keep you posted if the Safari on Mac issue is fixed.
luneducheval - This is a big feature a lot of people want, and we discussed it in our engineers meeting today. We are having them research what it will take to get this feature working for everyone. Again, I'll post an update when I get an idea of when we can put that into production. I promise they're working on it :)
KCS - If you are using a PC with Internet Explorer or Firefox, when you go to type in a post, there is a little smiley icon at the top middle/right part of the text box. You can click that to interject smileys into your post
