From MS euro compo rules:
"Opt in for communication from Microsoft. This is important; if we can't contact you to tell you that you've won, then you may not win! Not sure if you're opted in and want to participate in this great opportunity? Do this:
From the Xbox Dashboard, select Xbox Live.
1.Select Account Management.
2.Select Billing.
3.Select your account and enter the last four digits of the credit card number used for that account.
4.Select Information Sharing.
For Microsoft and our partners, choose Yes."
If one enters, and one's live subscribtion is about to end, does that also mean that automatically you have ordered xbox live for the next year onwards.
Why would I need/want to share my information with MS partners?
