Are there any Jabber (XMPP) apps out there that support jabber conferencing? I've tried several, and so far I can't get one that will just work with my work jabber + conferencing (jabber 'rooms').  They all seem mostly clunky.  Does anyone have a rec that has worked well for them for me to try?
I'm using Gibberbot. It is worth taking a look at. Free software, multi-protocol. Active developer community.  Definitely still in beta but that doesn't mean it won't do what you need.
