The Public Administrators are very similar to Administrators, but access to their tasks by special modules directly from the public LMS, without entering the administrative side. You can also assign a more limited number of functions such as:

• Management of Database Users
• Course Management 
• Management of Subscriptions
• Report Viewing

Another difference is on the display report, an Administrator may not create new reports but only see those made available from the New Reporting System and marked as "public".
