Please avoid delaying your games using the Vacation feature or Pause. Any participant using Vacation or Pause may be disqualified (and forfeit unfinished games) at the discretion of the Tournament Director.\n\n- Please make sure you understand the [**'Clock' settings**](https://github.com/online-go/online-go.com/wiki/Finding-(starting)-a-game#basic-time-controls-explained) before you join this tournament.  It typically takes 2-3 weeks to complete and you will need to log on and play at two well-spaced times most days to avoid losing by timeout.\n\n- If this suits you then, Bonne Partie....and please invite your friends. :)",
