With Tourney Machine you can enter time and coaching conflicts that your teams have in the system so that you don't have to remember. Once you have these restrictions entered, the system will warn you when you have violated one of the requests. It's a great way to meet the needs of your teams and keep your head on straight!
To add schedule restrictions go to Divisions, choose your division and click Schedule Restrictions
Now enter each team's schedule restrictions (the time your teams CANNOT play) and/or any restriction that a team has with other teams, like a coach that coaches more than one team (note that this does NOT prevent teams from being matched up against each other). Once your restrictions are entered click Save.
