Syntax: +FORWARD [@<altname>] [<bboard name>] <message>=<address>
This begins a message which is a forward of an existing message. The message
subject will be the text <fwd> followed by the original message subject.
The message text will begin with the text: <Forwarded message originally
by ______> with the original author's name in the blank. This will be
followed by the text of the original message and finally <End of forwarded
message>. You can add more to the message by using the commands listed in
HELP mail writing. The <address> you specify is a list of player names,
player dbrefs, mail groups, and/or bulletin boards.
Example 1: +forward 10=Jake
(Begins a forward of your 10th message, addressed to Jake.)
Example 2: +forward public 3=admins
(Begins a forward of the third posting on the public bboard to the admins
mailgroup.)
