My cousin just got a new 360 and wants to know if we can both use gamertags while playing multiplayer locally. I've seen in quick looks that the guys can use their actual gamertags on work 360s and their home 360. How do I do this?

You can download your gamertag onto your cousins console. I do that whenever I go to my friend's house for local co-op stuff.

You can also use a USB drive to store your profile for a quick login on other 360's, especially if your internet is slow.

Will that be in the system settings tab?
