We've previously seen how to install the Jabber cross-platform, and open, chat server. Sadly - some people insist on using the closed source IM clients. What should we do? There are three normal options: Install lots of clients Install a multiprotocol client Get jabber to understand the other protocols Option one will work - but I find having lots of clients open is confusing. Option 2 is one solution (gaim, bitlbee, trillian on windows etc) which works quite well. However - if you want to stay within the jabber world then option 3 is the one to go for.
