I’'ve gone through the client list on jabber.org looking for a free PPC client and have come up blank. IMOV works but is very clunky. I was looking for something a little easier to use that preferably supports emoticons.
I would recommend Pandion (which is what the Soapbox client is based on). You can find it at http://www.pandion.be and it’'s well tested with Jive Messenger.
