Multi-user Chat Room API
Steps:
1. create a room and named "sss@domain"
2. join it
3. invite someone like yyy (yyy is using the jabber client)
4. yyy's jabber client will be notified "xxx invite you to join sss@domain".
So, I want a nickname named by my self in invitee's notification. Just like "xxx invite you to join xxx's chat room"
How to do it?
