Bare bones description w/o reasons:
Provide an additional email command, similar to those for changing email delivery,
to give email only members the ability to have a specific, by number, message emailed direct to them.
e.g. email@example.com (with a subject of )14587
would cause that numbered message to be transmitted to that member's email address.
I'm not sure I'm understanding the idea. Is this so a member can have a message re-sent to them by the system rather than having to go to the web page to read it?
