Who: League Administrator, Match Secretary
From User Home Page go to Manage League > Modify League Settings
A league can decide which type of play characteristics to use (Gender, Age, and Play Level), then select within a type which specific characteristics to use. The ones selected will appear in drop down boxes when creating divisions and will also be used for setting referee payments. Go to Modify League Settings to select the types (default is all three) and Edit Play Characteristics to select the specific ones within a type.
The relative difficulty between play characteristics (e.g., U-10 versus U-14) can also be set on Edit Play Characteristics page. These difficulty levels are used to determine the difficulty of specific games and whether referees are experienced enough to officiate the games. See Referee Strength.
