Syntax: +BBNOTIFY <bboard>=<function>
**Admin-only**
Normally when a message is posted to a bboard, nobody is notified of this
event except the sender. Using this command you can specify a list of
people who are to be notified (if they are online) whenever a new message
is posted to board <name>. <function> must be a computationally
inexpensive function which returns a list of dbrefs of all the people to
be notified. Note that if a dark or hidden admin posts a message to the
bboard, only members of this list who are both online and can see that the
admin is online will receive the notification message. Also players set
haven or +os/haven never receive notification messages.
Example: +bbnotify admin-bb=\[get(#10000/adminlist)\]
