title: How should I edit or delete the default fields in moodle?
body: <p>I'm using moodle 3.0. While creating user, it displays too many extra fields like SkypeID, AimID etc. So is there any way to edit or delete these fields ?</p>
  
  <p>Also I want to add user profile fields in Grader report.Like, If I created 'Roll_No' field then it should be in the grader report.</p>
