We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
go down to xbox live from the menu, then either go right into a quick match and it will auto download the newest rosters for you and go into team management from XBOX LIVE menu and click download rosters...new rosters come out every week I believe on Thursdays
