    Tournament Maker

    Tournament Maker

    Software to help people run and organize tournaments.

    This program is intended for small tournament organizers. The goal is to allow organizers without much experience to setup and run a tournament without hours of preparation. Running a tournament is hard, especially when there are only a few people helping. With the software doing all the work, organizers will be more relaxed and it'll be a better experience for everyone. If you find this program useful, please donate to Food for the Hungry (http://fh.org/) or a charitable organization of your choosing. Quick Start Guide: https://sourceforge.net/p/tournamentmaker/wiki/Quick%20Start%20Guide/ ChangeLog: https://sourceforge.net/p/tournamentmaker/wiki/ChangeLog/ Please leave a review if you have time!
