In case you want to give the leadership of your guild, you use this command but you need to have a empty co-leader slot(if you dont have one then buy it) so by that the ex-leader becomes co.
@leader <botname>
Example:
FM Vish types: @leader Vish2
and Vish2 is the new leader, FM Vish now co.
and this btw
