How do I create a chat room for multiple participants using MIT Jabber?
With MIT's server, you create a room by trying to join it. The server will create the room if necessary.
You may need to know that the server for group chats on MIT Jabber is conference.mit.edu. Some Jabber clients do not have the ability to automatically detect the conference server for a given Jabber service, and in that case, you might have to specify the conference room as a chat contact in the form of email@example.com .
