XMPP: How to join group chat rooms?

How do I join group chat rooms with the instant messanger using the XMPP protocol. The only thing I can do is add them as contact but they always appear to be offline and I cannot see other chat members in that room.

I am sorry but it is not possible at the moment.

Alright, thank your for that answer.

Will this feature be available in version 5 or later?

I am not sure, implementation of this feature depends on the number of customers who will require this feature.

Did this feature ever make it in?

no unfortunately this feature is currently still not supported by the application.

I hope you understand,
