Microsoft has launched a new program which will allow users of Xbox Live to gain Microsoft Points. And all they have to do is, well, just do what they were doing already.
On the website it gives a brief list of tasks that can be performed and the amount of Microsoft Points you can get for doing said task.
One example is to renew your 12 Month Xbox Live Gold Membership, which would net you 200 Microsoft Points. Major Nelson also hinted that you can earn points by watching movies and playing games.
