A typical Manage Users page, showing three defined users: "Admin" - who is a global administrator - is able to change any content on the site and add, edit and delete users. "head" - who is also a global administrator, and "John Doe", who is allowed to manage content on the "Our School", "News" and "Calendar" pages.
Buttons are provided to add new users, edit users (change their name, email address and/or privileges) and to delete users.
