I got a PS3 for Christmas and I can't quite figure out the best way to set up the users in the house and link them to the online PS3 accounts. I guess you can either set-up several "master accounts" on a playstaion or one master account with several people under that account. Which is the best way to do this? The playstation implied that subaccounts wouldn't be able to purchase things or play 16+ games. Basically I want the best way to set up all the adults of the house.
