If you mean the smileys, like this
, click on "Go Advanced" when you reply to a thread, then you'll see some of them on your right-hand side, then there's a link to see ALL of them just below that sampling. For myself, I got tired of going through all that, so after opening the page with all the smileys, I just printed out a copy for myself, and keep that in my desk drawer, so I can look up the code if I want to use one I don't remember. If you know the code, you can just use the quick reply and type the code in yourself. Hope that made sense!
