Nice find man! And actually, Major Nelson has a ton of great info for all kinds of XBOX 360 stuff!
By the way, speaking of memberships, if you have a costco membership, they have one year Live cards for $40! Cheapest that I have seen anywhere. If it's not in the store, they always have it online and usually with free delivery. They also have a Messenger kit for only $60 that comes with - 1. A one year Gold Live membership; 2. The messenger chat pad for your controller; 3. Project Gotham Racing 4; and 4. A Live headset. It's a killer deal IMO.
