  Modified files:              
    /loncom/enrollment	Enrollment.pm 
  Log:
  Added check_user_status subroutine.  Used to determine if a course coordinator role is active in a course. Used by lonpopulate.pm when building the notification display table. Avoids the problem of stale end dates in the nohist_userroles table for the course.
