How to play 2 player online multiplayer in Call Of Duty: Modern Warfare 2?

I want to sign into 2 accounts, and play multiplayer online, PS3 QUESTION.





I don't want to hear about your Xbox, sorry.





I want to play team deathmatch etc, with 2 people signed into Playstation Network, not a guest account, because I have to keep repeating the experience and leveling up playing as a guest account.








So, how to sign into MW2 when you're player 2, and be able to play multiplayer online.





The answer that works gets best answered. :DHow to play 2 player online multiplayer in Call Of Duty: Modern Warfare 2?
