   =item * B<Blocking>: LON-CAPA can block display of e-mails that are 
   sent to a student during an online exam. A course coordinator or
   instructor can set an open and close date/time for scheduled online
   exams in a course. If a user uses the LON-CAPA internal messaging 
   system to display e-mails during the scheduled blocking event,  
   display of all e-mail sent during the blocking period will be 
   suppressed, and a message of explanation, including details of the 
   currently active blocking periods will be displayed instead. A user 
   who has a course coordinator or instructor role in a course will be
   unaffected by any blocking periods for the course, unless the user
   also has a student role in the course, AND has selected the student role.
