We got my 10 year old son a ps3 for his birthday but am now being hounded to get the network. You know, because "everyone else" has it. My 13 year old son has 360 live and I am even not to sure about that. I geuss my main question is this: When he joins the network, can he have a "group" that he can only interact with? Or if he is on a game, anyone and everyone can talk with him?
