In order to promote other administrators, you should have bureaucrat rights. In order to do so, go to this page on your wiki and contact the current bureaucrat to either make those promotions or promote you to bureaucrat to help. However, if he/she is inactive, you can adopt the wiki and you will be able to promote other admins.
