v_pin

  If your 'pin' variable is non-zero (whether a number, 'true' or 'on'), you
will be notified when any user connects to or disconnects from the server.  If
your 'pin' variable is zero ('false' or 'off'), you will not receive these
notifications.

  If you want to be notified only about certain users, read details in the
"notify" and "v_notifiedby" help files.
