Just wanted to point out for ease of use for all of you, I've revamped
http://gamerspouch.com and turned it into
http://sochl.com. You can add your gamertag to your account, and list out what 360 titles you have so you don't have to deal with all this manual updating of things over here.
If people own a game, they'll appear in an avatar list on that game's page (example:
http://sochl.com/game/2274 ), so if you're looking for people to play Vegas with, you can goto it and click the avatar to hook up with people, if they have their gamertag visible for others to see, you can even click a link that will auto-add them to your friends list (as long as you're signed onto xbox.com when you do).
More features are coming but its moving along nicely. If you've got any questions, lemme know.
