Well, let me think...
There's my other main hang:
http://www.wolfhome.com . it is a chat, but you actually take the form of a wolf with poses and stuff and you can see the others around you. Pretty neat. If anyone ever joins, I'm SilverFyre.
http://pub29.ezboard.com/bdragontails - a nice little dragon-themed message board....though I never go there anymore.
If I think of any more, I'll let you know.
