Can't change email here

I’d like to get notifications for replies on my posts, private messages, etc., but I can’t change my freaking email address here, and the one the Preferences section is showing they have is some 14 digit number, followed by @ and “email invalid.”

WTH?

Email hasn’t been enabled on here yet. The one in preferences is how they’re preventing them being sent. Once it’s enabled, your profile will be updated from your xbox live profile
