Prepares for you to compose a MOO email message to the players who either received or composed the indicated message from your collection. The usual editor is invoked (see "help editors" for details). The subject line for the new message will be initialized from that of the indicated message. If you leave off the message number, the reply will be to your current message, if that exists. In fact you may give a general message-sequence (see `help message-sequences') argument here, provided that it indicates only a single message (e.g., `@answer last:1')
If there is a Reply-to: field in the message you are @answer'ing, its contents will be used to initialize the To: line of your reply. Otherwise, a To: line is determined depending on whether you specified `sender', `all', or `followup' in the command line (or your .mail_options).
`sender' replies to sender only
`all' replies to sender and all original recipients
`followup' replies to first original recipient that is a non-player
(no effect if there are no non-player recipients).
`include' includes the text of the original message in your reply, `noinclude' does not.
`sender', `all', `followup', `include', and `noinclude' can all be abbreviated (e.g., `@answer i').
Defaults are `sender' and `noinclude', but you can change this by setting your .mail-options (see "help mail-options").
