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

                     90: 
                     91: Users can ask LON-CAPA to forward messages to conventional e-mail
                     92: addresses on their B<PREF> screen, but generally, LON-CAPA messages
1.132     www        93: are much more useful than traditional email can be made to be, even
1.58      bowersj2   94: with HTML support.
                     95: 
                     96: Right now, this document will cover just how to send a message, since
                     97: it is likely you will not need to programmatically read messages,
                     98: since lonmsg already implements that functionality.
