The "/announce" page:

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.
