You might know of www.360gl.com, and if you dont definately check them out. Here is the official description of them.
is first and foremost a Gaming League and Tournament Site, but we are building the Gamerbase into a useful tool for combining (and referring to) the great community sites that are out there.

Swing by and check them out, looks like they a Gears of War tournament coming up - you and all your team members can rack up a smooth 1600 MS Points, to bad I completely suck at Gears of War
