The Administrators are here to help operate this site. If need be, they can (un)protect and (un)delete pages, (un)block users and perform some other operations that are not available to regular users.
The Instructors have the necessary rights to administrate accounts of (their) students and the pages they create.
If you would like to become an administrator or instructor, please contact the Editors-in-Chief. At a later stage, more democratic procedures will be instituted.
