49: =head1 NAME
50:
51: Apache::lonmsg: supports internal messaging
52:
53: =head1 SYNOPSIS
54:
55: lonmsg provides routines for sending messages, receiving messages, and
56: a handler to allow users to read, send, and delete messages.
57:
58: =head1 OVERVIEW
59:
60: =head2 Messaging Overview
61:
62: X<messages>LON-CAPA provides an internal messaging system similar to
63: email, but customized for LON-CAPA's usage. LON-CAPA implements its
64: own messaging system, rather then building on top of email, because of
65: the features LON-CAPA messages can offer that conventional e-mail can
66: not:
67:
68: =over 4
69:
70: =item * B<Critical messages>: A message the recipient B<must>
71: acknowlegde receipt of before they are allowed to continue using the
72: system, preventing a user from claiming they never got a message
73:
74: =item * B<Receipts>: LON-CAPA can reliably send reciepts informing the
75: sender that it has been read; again, useful for preventing students
76: from claiming they did not see a message. (While conventional e-mail
77: has some reciept support, it's sporadic, e-mail client-specific, and
78: generally the receiver can opt to not send one, making it useless in
79: this case.)
80:
81: =item * B<Context>: LON-CAPA knows about the sender, such as where
82: they are in a course. When a student mails an instructor asking for
83: help on the problem, the instructor receives not just the student's
84: question, but all submissions the student has made up to that point,
85: the user's rendering of the problem, and the complete view the student
86: saw of the resource, including discussion up to that point. Finally,
87: the instructor is reading all of this inside of LON-CAPA, not their
88: email program, so they have full access to LON-CAPA's grading
89: interface, or other features they may wish to use in response to the
90: student's query.
91:
92: =back
93:
94: Users can ask LON-CAPA to forward messages to conventional e-mail
95: addresses on their B<PREF> screen, but generally, LON-CAPA messages
96: are much more useful then traditional email can be made to be, even
97: with HTML support.
98:
99: Right now, this document will cover just how to send a message, since
100: it is likely you will not need to programmatically read messages,
101: since lonmsg already implements that functionality.
