Up top on the main forum index page is this: CHAT (Soc,Sup, #) if you click on the number (it tells you how many ppl are in chat, if any) it will give you a list of who's in chat.

If you click on Soc or Sup.. then it will take you directly to that chat room (social chat room, or support chat room.) If you click on CHAT, then you go into the main chat room, Psych Central chat room.
