Leader transfer

This is a simple question , i try change the leader of my clan to other char one friend , but when i transfer the leader nothing happen, whatt is the time i need waiting for the transfer?

You need to wait Wednesday's maintenance time. After that the clan leadership will be regularly transferred.

You have to type the clan member's name as it is. Capitals-Non Capitals.
If someone wants to make me leader has to enter name BeEtKraFt, not beetkraft.
