The user's tool allows the user to submit a message (after logging
in).

The user needs to provide:
 - the department or org for which they're submitting the message
 - the audience(s) (student, faculty, staff, or other)
   NOTE: students are not given the 'other' audience option
 - A title/headline
 - the message itself

The user may optionally provide
- an active date (the date on which they'd like the message to appear)
- a long message (for things that require more info than the small
space; a link to it is automatically added in the message sent out)
- an Advance Notice message (a very short version fo the message, to
be published ahead of the normal message)
- an Advance Notice date (the date on which to publish the advance
notice message; must be at elast three days before the active date)

This data is then saved to the DB, along with various user info
grabbed from LDAP (name, phone, email, etc.).
