@wall

COMMAND: @wall/<switches> <message>

With no switches, shouts <message> to every connected player or to every connected wizard, prefixed by either ‘Announcement:’ (if for everyone) or ‘Broadcast:’ (if for wizards). The following switches can be used to get the described effects:

/emit      - Format the message as an emit (ie send just <message>).
/pose      - Format the message as a pose (ie <yourname> <message>).
/wizard    - Only send the message to connected wizards.
/admin     - Send the message to connected wizards and royalty.
/no_prefix - Don't prepend 'Announcement:' or 'Broadcast:' to the message.

If neither /emit or /pose are used, you can format the message one of several ways by specifying ‘:’, ‘;’, or ‘"’ as the first character of the message. ‘:’ and ‘;’ format the message as if /pose were specified, except that ‘;’ does not insert a space between your name and the message. ‘"’ formats the message in normal @wall format (this is the default). The message is also written to the log file.
