Administrator is the only permission in Publishing, which has access to all Publishing features.
All Organization Administrators have access to Publishing and can add Publishing Administrators.
From the People tab, type the name of a person you'd like to give access to.
That person will receive an email, which give them instructions on how to access Publishing.
You cannot remove an Organization Administrator from Publishing, but you can remove any Publishing Administrator.
Click the dropdown arrow, and then choose Remove administrator.
