Well let see it registered, then he fills the form to submit an application to the clan community, it shall consider and approve - then give it to a group forum (clan tag), and then he drives his uuid and gets right to the forum. But who said that the user will not indulge? then it adequate? that prevents him to enter another uuid player himself will take a person in the clan community? Therefore, I ask to add a line in the groups section of the forum on the number of allowed uuid or 1 or more.
