Checking GUID's

I understand how to do it if your running BC2 Gaurdian, but if you're on the other teams server, how do you get theirs?

If they have the TWL flag set on their server you can query the IDs with PBBans.

League Roster Check
Paste in the IPort of the server, you can get this on someone's xfire status I believe.

If it tells you a player could not be found on the league you'll have to copy-paste their ID to find them manually.

Thanks for the quick response.
