People won't just join your clan for no reason... you have to give them a reason for joining.
Are you inviting members? If so, who? What can you offer them? Why should they join your clan and not someone else's more established clan? So many questions....
Try to think back on the time when you joined the 3 clans you're a member of. What made you join?
When you find out, try the same "trick" on others π
