   34: =head1 NAME
   35: 
   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: 
   77: =back
   78: 
   79: Users can ask LON-CAPA to forward messages to conventional e-mail
   80: addresses on their B<PREF> screen, but generally, LON-CAPA messages
   81: are much more useful then traditional email can be made to be, even
   82: with HTML support.
   83: 
   84: Right now, this document will cover just how to send a message, since
   85: it is likely you will not need to programmatically read messages,
   86: since lonmsg already implements that functionality.
