=head1 NAME
Apache::lonmsgdisplay: supports internal messaging
=head1 SYNOPSIS
lonmsgdisplay provides a handler to allow users to read, send,
and delete messages, and to create and delete message folders,
and to move messages between folders.
=head1 OVERVIEW
=head2 Messaging Overview
X<messages>LON-CAPA provides an internal messaging system similar to
email, but customized for LON-CAPA's usage. LON-CAPA implements its
own messaging system, rather then building on top of email, because of
the features LON-CAPA messages can offer that conventional e-mail can
not:
=over 4
=item * B<Critical messages>: A message the recipient B<must>
acknowlegde receipt of before they are allowed to continue using the
system, preventing a user from claiming they never got a message
=item * B<Receipts>: LON-CAPA can reliably send reciepts informing the
sender that it has been read; again, useful for preventing students
from claiming they did not see a message. (While conventional e-mail
has some reciept support, it's sporadic, e-mail client-specific, and
generally the receiver can opt to not send one, making it useless in
this case.)
=item * B<Context>: LON-CAPA knows about the sender, such as where
they are in a course. When a student mails an instructor asking for
help on the problem, the instructor receives not just the student's
question, but all submissions the student has made up to that point,
the user's rendering of the problem, and the complete view the student
saw of the resource, including discussion up to that point. Finally,
the instructor is reading all of this inside of LON-CAPA, not their
email program, so they have full access to LON-CAPA's grading
interface, or other features they may wish to use in response to the
student's query.
=item * B<Blocking>: LON-CAPA can block selected communication
features for students 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.
=back
Users can ask LON-CAPA to forward messages to conventional e-mail
addresses on their B<PREF> screen, but generally, LON-CAPA messages
are much more useful than traditional email can be made to be, even
with HTML support.
