Which UT2k3 mods work in 2k4?

[Subjective Effect]

. . if any? I've been investigating the Make Something Unreal stuff and overall it is really amazing. But since the competition started pre-2k4 will any of them work for 2k4 except for the current phase (which Alien Swarm is in)?

Alot is being converted, and will be released over the next few days.

Yeah, no UT2k3 mods work with UT2004 without some work. But I know Siege and some other mod whose name escapes me from the Make Something Unreal contest have already been converted.

And of course there's about 18 mods that will be released at the end of the month for phase 3.
