I'm I signed up for all? What about being referred by someone during trades, does that work or it's only a one time deal?
You can sign up for the individual Free4Me sites under different people. But after you've created an initial account on one site, you actually choose a 'Log In' option after confirming who referred you. Use your previous username/password from the first Free4Me site you signed up at, his sites all use the same user database.
It's a very nice system, and it's the BEST network out there right now!
