Sign ups begin for the Preview program on Xbox 360
Microsoft has invited Xbox Live users to sign up for Facebook and Twitter ahead of their launch on the service to enable them to test their functionality.
According to Major Nelsons blog, Microsoft is seeking "multiple thousands of participants" and the beta is open to to worldwide users. Gold members will be given preference, although not to the exclusion of Silver ones.
An official date for the roll out of the social sites on Live is yet to be confirmed, but rumours have suggested a November 17 date.
Facebook, Twitter and Last.fm integration with 360 was announced at E3 this year. Nintendo added a Facebook Connect feature to the DSi in August.
