   34: =head1 NAME
   35: 
   36: Apache::lonmsgdisplay: supports internal messaging
   37: 
   38: =head1 SYNOPSIS
   39: 
   40: lonmsgdisplay provides a handler to allow users to read, send, 
   41: and delete messages, and to create and delete message folders,
   42: and to move messages between folders.
   43: 
   44: =head1 OVERVIEW
   45: 
   46: =head2 Messaging Overview
   47: 
   48: X<messages>LON-CAPA provides an internal messaging system similar to
   49: email, but customized for LON-CAPA's usage. LON-CAPA implements its
   50: own messaging system, rather then building on top of email, because of
   51: the features LON-CAPA messages can offer that conventional e-mail can
   52: not:
   53: 
   54: =over 4
   55: 
   56: =item * B<Critical messages>: A message the recipient B<must>
   57: acknowlegde receipt of before they are allowed to continue using the
   58: system, preventing a user from claiming they never got a message
   59: 
   60: =item * B<Receipts>: LON-CAPA can reliably send reciepts informing the
   61: sender that it has been read; again, useful for preventing students
   62: from claiming they did not see a message. (While conventional e-mail
   63: has some reciept support, it's sporadic, e-mail client-specific, and
   64: generally the receiver can opt to not send one, making it useless in
   65: this case.)
   66: 
   67: =item * B<Context>: LON-CAPA knows about the sender, such as where
   68: they are in a course. When a student mails an instructor asking for
   69: help on the problem, the instructor receives not just the student's
   70: question, but all submissions the student has made up to that point,
   71: the user's rendering of the problem, and the complete view the student
   72: saw of the resource, including discussion up to that point. Finally,
   73: the instructor is reading all of this inside of LON-CAPA, not their
   74: email program, so they have full access to LON-CAPA's grading
   75: interface, or other features they may wish to use in response to the
   76: student's query.
   77: 
   78: =item * B<Blocking>: LON-CAPA can block selected communication 
   79: features for students during an online exam. A course coordinator or
   80: instructor can set an open and close date/time for scheduled online
   81: exams in a course. If a user uses the LON-CAPA internal messaging 
   82: system to display e-mails during the scheduled blocking event,  
   83: display of all e-mail sent during the blocking period will be 
   84: suppressed, and a message of explanation, including details of the 
   85: currently active blocking periods will be displayed instead. A user 
   86: who has a course coordinator or instructor role in a course will be
   87: unaffected by any blocking periods for the course, unless the user
   88: also has a student role in the course, AND has selected the student role.
   89: 
   90: =back
   91: 
   92: Users can ask LON-CAPA to forward messages to conventional e-mail
   93: addresses on their B<PREF> screen, but generally, LON-CAPA messages
   94: are much more useful than traditional email can be made to be, even
   95: with HTML support.
