Invite Members -> This is the tool the administrators can use in order to invite other people.
Member Ranks -> Each rank in a gang allows you gang power. At level 85 you have the power to invite and accept people into a gang. At level 95 you have the power to dispense money from the treasury to gang members. If at any time the leader leaves the gang the person with the highest power becomes the new leader. Only the leader can control member ranks. Also keep in mind if someones rank is higher then someone elses they have the power to kick that person from the gang.
