Want to give the upcoming Xbox Dashboard a whirl before it is officially released? Microsoft's Major Nelson has posted details about a preview program that the public can participate in.
Sign up and you'll be able to test out the new design that focuses around Kinect, the "Beacon" system, deeper Facebook integration and, perhaps best of all, the cloud storage system for game saves and Live profiles, meaning the days of being forced to recover your Gamertag should be over. Features like the Party Chat and online multiplayer will continue to work with those who don't join the preview program, so you shouldn't have to worry about reduced functionality.
