Xbox Live will launch in Fall of 2002, but a few lucky gamers will get into the Beta-testing program that launches this summer. You can try out the service and games in their pre-release forms, plus tell all your friends that you were one of the first people in the world to go live!
Note: Not everyone who signs up for the Beta program will be selected. The information in your user profile must meet the necessary criteria in order to be selected.
