Chat Rooms


You can set up a dynamic chat rooms by selecting New Chat…” in your chat client and adding multiple participants. Dynamic chat rooms close shortly after the last participant leaves the room. Dynamic chat rooms are the preferred method for multiparticipant chats.


Persistent or static chat rooms can be set up to support groups or activities.

If you are interested in a persistent chat room, send your request to the Service Desk.
