I am trying to figure out how to add a second administrator and cannot find a way to do that. It does not explain how in any of the help sections I could find.
Rob,
I don't know if this is the best way, but what I do is create a new role called 'admin' or 'super user' (go to 'administer/access control' and select the 'roles' tab) and then grant that role privileges (the 'administer/access control/permissions tab) to administer some or all of the site. Then enable that role for any users who should have admin privileges.
