Starcraft 2: Third Party Maps / Mods / Stuff.

[SurfD]

So, I have finished the currently available SC2 Campain, and am looking for new things to try, so I was wondering: Does anyone have any reccomendations for any Third Party Maps.

Or did Blizzards stance on distribution methods and use of their mod tools cramp that scene too heavily for SC2?

No good Tower Defense maps or things like that?

I've heard someone went and remade the entire Starcraft 1 campaign in Starcraft 2 editor (complete with all the SC1 unit stats and such).  Might keep you busy for a while if you want to revisit that while looking for more.  I'm not really up on SC2 right now though so I don't really know anything else.

Left4dead is a fun two player coop. You have to turn on custom maps, then it's listed under 6 player maps.
