Only the owner or the administrator of your Organization can give other users who are already members of your Organization administrator rights. 

Select the Organization in the Service tree view and press the edit button in the Service cursor menu bar. Under the section “Organization Members” you will need to select the user you would like to apply the changes for. 

You may assign a selected user administrator rights if you tick the “Admin” box. To confirm the changes you need to press “Save” button above the member list.

Likewise, you may revoke a selected user administrator rights by unticking the "Admin" box. To confirm the changes you need to press “Save” button above the member list.
