What if Noteflight offered it's own copyright system? That way people couldn't steal your score and claim it as their own. What if everytime you released a score, the copyright system popped up and began asking questions like is this original? If it is NOT original, then the copyright system would stop and allow you to released the score as normal. But if it IS original, it could proceed to ask questions such as name, date of birth, email adress, gender, etc.
