v_open

  If your 'open' variable is non-zero (whether a number, 'true' or 'on'), you
are willing to accept match requests.  If your 'open' variable is zero
('false' or 'off'), you will not receive match requests.  The "open" command
toggles the 'open' variable on and off.  Players who are not open for match
requests have the ":" designation next to their handles in "who" displays and
are not available for matches.
