I just found out there's a way to "register" your username at tenhou, and then have access to replays, personal rankings, average score and other awesome stuff.

However, I can't for the life of me replicate what I did to try and guide a friend to register too. Does anyone know exactly how to pull it off?

What I did was click random shit at the login screen, then afterwards instead of my username on the name field it just automatically pastes an ID code
