Bets,
Don't worry, it's not you.
These are most likely idle sessions that have timed out. If someone exits their browser, or goes to another address, the server will not register this action as logging out. You have to execute the logout command or hit the "X" button at the top-right corner of the chat window to logout properly. Otherwise, you will be hanging in "limbo" until the server times you out. I am hoping later versions will address this issue. There also may be something that I can do to make this work better; I'll look into it.
The logins are done using your account on the Conversation Board. If you are logged into the Conversation Board, you can go straight into the chat room.
