[quote name='Zuttasoxx']I am up for it.. It's my first game share here on CAG so how does it go?[/QUOTE]
It's fairly simple really, if a little intimidating at first. You simply send the money through paypal to the sellers/hosts email address. Once they see that they've received the money they then give you the PSN login details (email and password). You create a new account on the PS3 (it's on the very left menu on the XMB) and login to it, scroll over to the PSN icon on the XMB and click "Sign up for the Playstation Network", click the option that you're an existing user (not a new one), input the email and password and boom. Now just login, go to the store, and access the download history list from the upper right corner of the store.
I'll throw you a PM with the Paypal details.
