A web-form, available to users with the "Send-Announcement" or "A"
capability, that allows one to send announcements to whomever
has subscribed to receive announcements.  The administrator can
also send a message to an arbitrary email address and/or to all
subscribers regardless of whether or not they have elected to
receive announcements.
