...We've had quite a ride since you left. Maybe a gif from the Matrix would have been better.
First was the migration away from the original server. Most of those in charge went MIA so we were basically on a moving train with no captain. It's somehow still working, but this new 2.0 server was started so we can have control over it.
There have been quite a few mods since, but most of them still fit the genre of the original Omni server. It's mostly new vehicles.
A few months ago Epic Games announced they are closing the ut2004 master server. Luckily the user base was tech savvy enough to create a new one within a couple of days. You cannot buy the game on steam anymore unfortunately.
