Basic rules
1: don't make these outrageously long names--nobody likes that.
2: please, don't just sign up and never play--that would be just cruel
3: be original. I know Naruto games with people who go around calling themselves "Kakashi01, Kakashi08, Kakashi224, Sasuke334, Lee22", and all that. So Please, make up your own character, don't always go with popular guys like Hitusagaya and Ichigo and call yourself some uber-unoriginal name like "Ichigo24".
4: don't have any offensive names like "n_gger" or "biatch".
