Linking Xbox LIVE account to Facebook?

[Kit]

To show achievements, see friends' gamertags and whatnot.

The email account for my LIVE is different from my Facebook account's email.

How can I link them?

[Yuuuup]

To add or remove a linked account, navigate to "Linked Accounts" section of your Account Settings page. Click "change" to see a list of all of the accounts that are currently linked to your Facebook account.

To link a new account, select an account type from the drop-down menu and click "Link New Account." Enter your Facebook password in the box that appears and click "confirm." Another box will appear asking you to sign into the account you wish to link (for example, your Gmail account).

To remove a linked account, simply click the "remove" button located next to the account.
