Alright
well this ones just an even simpler guide, im just gonna explain how people like share games with each other or download content from another persons account to their PS3.

By the way your gonna want to be careful with this in case you get hacked, its gotta be someone you trust, or dont mind putting your account and whatevers on it on the line.

1. after you have the person u wanna trade with or download content from, and you make a new user account, as in from the users section at the very right of your XMB/Menu Screen or whatever you call it, dashboard. and you just create a new user with whatever name you want, it could be their username, or just some random letters.

2. Once you have their login, Email and Password, you login to the new user and you go to the store/PS store and you press login to existing account and you enter the user and pass, so once you enter that it lags a bit because its loading the account and you just go to the store and go to the download list and download whatever you want.

Keep in mind that if your doing this, you can only have 5 active PS3's at a time so you can only trade/give content to 4 other people unless they deactivate theyre PS3 from your account and you have another use.

and if your the one giving the content, its suggested you change your original password then once they download, usually give them around a minute and change the password back and login and you should be good. what i normally do is change the pass to some part of theyre username with a 1 at the end to make it easier then change it back to my original.

Now you have your downloads from other people ect.
