Yeah, wiki admins are automatically chat moderators. Admins can also assign other people chat mod status within the chat itself.

People have to log in to use the chat... I'm not sure how you saw an anonymous user in there, but let us know if it happens again!

We don't have a "close room" option yet on the private rooms. They get cleared when you leave the chat, so at least you won't have a long list of them following you around for days. :)
