IDETalk support for forums

Where I work there is a forum system . Is it possible to join a forum using IDEtalk ? The forums are visible with a jabber client
Also, how does IDEtalk access the contact list from your messenging client ? it looks like the contact list synchronizes automatically between IDEtalk and the corporate jabber client.
Last thing, some of our forums have addresses with embedded spaces, so I was wondering whether this is supported as when one adds jabber ids spaces are used as separator.
