So, this is my question a bit explained:

I've got 1 ps3, so i've got also 1 version of mw3, bud i play it, and my little brother also plays it. Is it possible to create 2 elite accounts and use it on 1 ps3, one way of another, so we can both have the profits of elite and not sharing 1 account.

Hope you can help me,and so not, thanks anyway!
