Taken from another forum I frequent:
Microsoft have today announced a new online-only event for Xbox 360 owners, named Xtival 07. The event, which runs from the 23rd to the 26th of November will provide exclusive downloads, competitions and more for Xbox 360 owners, including something rather funky
FREE Xbox Live Gold for the duration of the event!
All you need to do to take advantage of this promotion, is plug your 360 into your network. Youll instantly find any Silver accounts have been converted to Gold for the duration of the event. Only if youre in Europe, though!
It's the first deal I've posted please go easy on me!!
