Am I allowed to use the Private Chat room with another paid member of ST?

Use "The Every Day Chat Room" to talk to anyone and the "Gold Star Chats" to talk to other Premium members.

"Private Chat" is a room we use for meetings - the Big GTG organizers are using it. I will change the description of that chat room so that is more clear.

You can't have a chat that is completely private. Even in the Gold Star Chat Room, someone can join in, but you see their name in the list. For a completely private exchange, use private messages.

Thanks for the explanation, Pauline.

I moved the discussion of Callie's problems to a new thread.
