Double Happy is a social Tennis Doubles event organizer. It is designed to make it simple (and even fun) to run social doubles events for Tennis, Badminton, Table Tennis, or any activity where 2 people play as partners against 2 others. A typical scenario. You have a number of players, often of varying ability, and a number of courts. You want to run an event where each person plays several games with different partners and against different opponents. Double Happy will generate, round by round, a mix of players to be assigned to each court for up to 21 courts and 200 players. However, you can influence the mix for each round by using the following features; * Grouping players by any criteria you like such as gender or skill. * Selecting one of 5 different Mix Types that will generate a different mix of players based on the player groups. * Resting players who want to take time out. * Manually over-riding any player assignments. Double Happy is best used live for the most flexibility. This allows you to add new players as they arrive, rest players if they request it, and generally react to whatever situation arises. If another court suddenly becomes available then no problem - just tell Double Happy and it will start using the extra court. Double Happy also has a built-in Timer that you can use to countdown the time that a Round has been on court. In the meantime you can get on with preparing the next Round.If you know in advance of your event just who will be playing, and on how many courts, then Double Happy can be used to prepare and print all the Rounds in advance.You can learn more about Double Happy by visiting www.promato.com/doublehappy
