• +allavail+ holds tournament start until all registered pairs are available. Returns a message to the host, informing them who is not available. Please note that this does not work for Swiss Teams format.
• +howell+ turns a mitchell movement into howell. Documented here.
  • +hm18+ is used together with +howell+ Turns a mitchell movement into howell if there are less than 7 tables. Else it runs as a mitchell. Works only for pair tournaments of exactly 18 boards. Documented here.
  • +roundsX+ is used together with +howell+ Runs a partial howell tournament, which stops after X rounds. Documented here.
