Back in the dim, dark recesses of time ...
... I setup and administered a number of game servers for a friend of mine that had a computer store and ran monthly LAN parties there after hours. One of the most popular games, by far, was Unreal Tournament 2004. The game servers were eventually moved to being run from my home, and then gamenights became strictly online (allowing people to do pick-up games on the servers whenever they wanted), then people moved away, got married and had kids, etc., etc. ...
And, through it all, I kept the servers running. I've now migrated onto the fourth game server on my network, and here is the information you'll need to get connected to the UT2K4 server currently running here. Enjoy.
