Last week, I wrote a small introduction to Gaim, a great chat client written for GTK. The functionality of Gaim has gotten quite advanced, which has made it one of the leading-edge open-source chat clients currently available. Granted, it does not yet support things like video chat and audio chat; filesharing is still a little buggy. However, according to the program's author, Sean Egan, who has recently been hired by Google, these things will become available within a month's time.
Here we explore the options of what Gaim currently offers. Primarily written for SUSE/Novell, but applies to gaim in general as well.
