Hey folks!
I'm looking for some software or service to manage the referees in my sports club.
I want to assign people (and maybe even groups of people) to a specific game and have an automatic notification for them. Then the assigned referee should be able to confirm or deny the assignment.
Some extras would be something like a counter of how many games each specific referee has done and some kind of calendar where the referees can block some dates where they don't want to have a game.

Any suggestions? Thanks in advance!
