I posted this information by request in the general discussion forum, but it really belongs here, so here we go.
I'm admin in a Danish gaming community. We run a Christmas themed UT2004 server throughout December. There's something unbelievably hilarious about running around in Santa's workshop and blowing away other players wearing Santa hats and bags of presents over their shoulders. Or a round of Capture The Tree, priceless :-D
You can find the game-monitor page for the server [url=http://www.game-monitor.com/ut2004_GameServer/78.46.72.40:7777/WanParty.dk_XMAS-PARTY_2008.html]here[/url].
And here are a few screenshots from the server, just to show you a bit of what you can expect.

Be warned that there are quite a few mutators and stuff you'll need to play. I'm not sure everything is in the cache, so you might want to download our X-mas pack and install it beforehand. You can download the pack through this link. The pack is 214 MB, and contains all the maps, music, etc. It's packed as a self-extracting 7zip file (if I recall correctly). It contains no trojans, viruses, or anything of the sort. We did not make any of the content ourselves, but put the pack together from content that is freely available.
The server is public when we're not running an event (which is every 6 days), at which time it is password-protected and members-only. I'm afraid membership is restricted to Danish-speaking people (we use Teamspeak for events, and a few of our older members speak almost no English at all), but outside of event time, you're very welcome on the server. At the moment it runs with a minimum of 4 players, meaning that if there are less than 4 people on it, the rest of the slots will be filled by bots.
That being said, if you are the type to be offended by scantily clad women, don't log onto our server. Most of the X-mas maps have posters of such in them, and what link #2 is showing, is what happens at the end of a match. Two very lightly dressed girls in santa hats teleport in to dance provocatively on either side of the winner. If you can't handle that, please stay away.
Happy X-mas fragging :-D

downloaded the pack, haven't had much time for gaming recently.. but expect me to show up sometime. :)

Let's try to coordinate something one of these days, otherwise you're most likely to be playing 3 bots by yourself. The server isn't exactly busy most of the time :-/

I frequent the GOG Irc Channel while I'm at home, that is the usual place people meet up to play games. Otherwise I have steam and my name is weclock.

Well, I found the IRC channel. I'll try to hang out there as often as I can.
