[Juser] Group chat capability in ICQ transport

[Rodolfo Medina]

Hi, listers.

With MS Windows and ICQ there installed I can access public
group chatrooms such as `#20 something', `#French', `#Computers'
and many others.
I'm trying to do so with jabber (and other linux applications: 
also gaim, centericq, licq) but don't manage to:
all the servers I tried (at http://www.xmpp.net/bycountry.shtml)
do not support, it seems, group chat.
I followed the jabber user guide at:

 http://www.jabber.org/user/userguide/

. Please, any help?
Is it possible to perform with Linux all ICQ's features
(including group chatting)?

Thanks,
Rodolfo
