No email needed. Use your real name — that is what you will sign in with, so there is no username to remember. You will get your own Mastermind ID and start at a 1200 rating; your first rated game at the café is what starts moving it.
Played at the café before? Sign in with your old username instead — signing up again starts a second account at 1200 and leaves your games behind.
