+=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.
