The "r" in the toplist

[Shagileo]

Yep, it's a reserved playername so others can't take it from you.
We advise every TrackBase user to reserve his/her name. It will allow you to enable TB's special 'Playlock' feature, to maintain control over ranked sessions for your username.

There are of course more features, like creating a buddy list etc.

4chan would say \r\ is for requested
