From Elendor
Syntax: +REAUTHOR [@<altname>] <bboard> <message>=<player>
This allows players who administrate bulletin boards to reassign the "From"
fields of messages on the bulletin board to different players. This is
important because certain boards are not postable directly and players
must ask the board administrator to post a message on their behalf. The
board administrator can then change the "From" field to the original
author after posting the author's message. In order to use this command,
you must pass the board's adminlock.
