title: Use Case diagram UML: Admin privileges
body: <p>I have three main actors in my Use Case diagram, Admin, SuperAdmin, User.
  Now SuperAdmin CRUD Admins, each admin have different privilege, 3 different privileges to be precise.
  My question is do I have to create 3 types of Admins (so 2 more actors) which each admin is represented according to his privilege, or just create a single Admin actor &amp; link it to all three use cases (the 3 privileges)?</p>
  
  <p>I am new user of UML &amp; This is my 1st project.</p>
