Does anyone here play Trackmania? If so, can you recommend some fun servers?

I bought the game only a couple of weeks ago and I'm finding it really good fun, albeit just as an alternative for when I get bored of WoW or shooting people.

For those who don't know it, TM is a basic racing game that's played using keyboard controls. The fun comes from user-created maps that have insane speeds, jumps, loops, vertical banked bends, holes in the tracks, etc. It's probably more of a puzzle-platformer than a racing game.
