Group chats in bitlbee using most Jabber servers
See GtalkGroupchats for Google Talk accounts specifically.
1. First of all, add the account if you haven't already, eg:
account add jabber me@myjabberserver.com [password]
2. Then add the chatroom using the chat add command. Most jabber room names take the form roomname@conference.server.
chat add [account] myroom@conference.myjabberserver.com
You can optionally append a different name for the channel to be created; it will default to the room name. [Aside: chat add is shorthand for a bunch of channel commands.]
3. If the chatroom is password protected, set the password:
channel [id] set password [password]
4. Activate your accounts
account on
5. Join the channel now associated with the group chat (chat list if you are unsure)
/join #myroom
Ad hoc chats
If you are running bitlbee 3.0.5 or above, you can create ad-hoc chats with people using the standard approach for all protocols of /join #something and /invite people.
