Just a warning there are xbox hackers hacking e-mail account getting you to register on there website ...They use the info to gain access to your e-mail accounts and from there can take over your xbox live account...This is the message i got (I just got 5000 Microsoft points by registering on -Link-. I won't put link on in case someone decides to visit the link.
They took over my accounts and changed my passwords security questions and then the debited my credit card to sell the xbox live account on the black market.
Just thought i'd warn everyone.
Cheers
