Give managers ability to change players responses to invitations, attendance options. Allow to register players without their email confirmation. We get written application form from parents and don't have the need for parents to register in the app. However still we would like to manage our members using your app. That would require to allow team and club managers to change options of players. Also, sometime player give you a call and can not use app for any reason. That way it would be great if managers can check the attendance options on behalf of the players.
