I don't think there is and i'm glad if there is none, it would open the floodgates for all the MW2 10th prestiege lobby invites for money, so here hopeing there is no way you can search for id's like that.
Yes, there is a place - kinda.
The US PlayStation site has the functionality to search for a gamer and check out their Trophies, although unlike Xbox you can't message them, or add them as a friend, but I'm sure that may come over time.
Just enter an ID after the = sign.
but can you add that friend that you look up or do you have to do that via your console only?
Hey, recently I got into a game with two people and had alot of fun with them. Randomly the game decides to kick me because I couldn't reconnect, so now I'm stuck not knowing what their names were. Is there anyway to search their names and see a list of similar ones?
Yes, You can go to the PS Menu on your ps3 and go to the "Friends" row. After you do that, you go down till you see "Players Met" click and you'll see the latest players you've met. If you played this game a few months ago then you may not be able to see that persons ID.
