Status/messages
The Status packet is free-field format that lets each station announce his current mission or application or contact information or any other information or data of immediate use to surrounding activities. The message packet can be used for point-to-point messages, bulletins, announcements or even email. Bulletins and Announcements are treated specially and displayed on a single "community Bulletin board". This community bulletin board is fixed size and all bulletins from all posters are sorted onto this display. The intent of this display is to be consistent and identical for all viewers so that all participants are seeing the same information at the same time. Since lines are sorted onto the display, then individual posters can edit, update, or delete individual lines of their bulletins at any time to keep the bulletin board up-to-date to all viewers.
All APRS messages are delivered live in real-time to on-line recipients. Messages are not stored and forwarded, but retried until timed out. The delivery of these messages is global, since the APRS-IS distributes all packets to all other igates in the world and those that are messages will actually go back to RF via any IGate that is near the intended recipient.
A special case message can be sent to EMAIL and these messages are pulled off the real-time APRS-IS by the WU2Z Email engine and wrapped into a standard Internet Email protocol and forwarded into regular internet email.

Famous quotes containing the words status and/or messages:
“A genuine Left doesn’t consider anyone’s suffering irrelevant or titillating; nor does it function as a microcosm of capitalist economy, with men competing for power and status at the top, and women doing all the work at the bottom.... Goodbye to all that.”
—Robin Morgan (b. 1941)
“The first of the undecoded messages read: “Popeye sits in thunder,
Unthought of. From that shoebox of an apartment,
From livid curtain’s hue, a tangram emerges: a country.””
—John Ashbery (b. 1927)
