Welcome back!
Just for clarification you can't get your old login info back, only the ingame name (unless some evil creep hasn't taken it). This to prevent you to "create" a "temporary" account which you can't remember or reproduce. I'm not saying you would do so, but just in case... There's enough people called "+9oesuer" with the password "094i rgsnx" filling rosters just because they're too lazy to create memorable login info.
Skuzzy, correct me if I'm wrong here.
