Team Officials (Team Managers and Coaches) can see the referees that are signed up for your game, as well as what positions are still not filled.
Step 1: After logging in and going to your team's page, go to the Games.
Step 2: Each game has a list of the referee positions needed and referees signed up for the game. This information is located in the bottom right corner of each game's list card.
Each position not filled is shown red with the position needed text (eg. "CR - Needed"). Each position that is filled will have the referee's name listed along with the position.
