I wrote GICQ around 1997, to address a lack of Linux-based ICQ clients. It was very minimalistic, but for a time it worked very well. I learned a lot writing it, but it's been unmaintained for over five years, and will almost certainly not compile or work under any modern Linux system.
If you're a cyberarcheologist, it may still have a web page up at http://gicq.sourceforge.net/.
If you happen to need an advanced, affordable web host, check out Telana Internet Services.
