I think you would just have to create an account with the same name as the one from where the data originated from, but I think it is still more of an hassle than for what it's worth. Plus it would probably be easier to just make the customs instead of trying to import and export data. Even easier to just bring your console with you.
Lastly, people should have a few customs of the most used characters on their console anyway. I hate playing with just the default character costumes. There's plenty of formulas in the CAS subforum to choose from. Just take a few minutes and make some.
It's not the account name im sure lol. It just wudnt make sense if u had sum1s user cause you had the same name. It shud be linked with the online account so you'd have to register your account onto their ps3 to use ure save im guessin.
But either way yeah, too much hassle to go through. And Super_villian i think you can get that through DLC or a load of honors.
