Very good idea, I'm certain that many people just create a clan as soon as they register, almost as part of the registration process. However, the limit should be 2-3 i think. And then the clan gets wiped if it has less than the min number after a certain time period (so if a clan drops a member, they have a recovery time). I think it would be possible for Jits to just flag the clan as not having the min number of members, so that it can be resumed with all details intact?
