Fall 2020 Changes

MOSSL will be switching to Demosphere for the 2020 Fall season. We think this will be an improvement over the old scheduling system.  Please watch for updates.  We appreciate your patience as we make the transition.  

All current referees in Game Officials will be merged to our new Demopshere account.  You will not need to re-register in the new system.  Once set up is complete you will be sent a link and instructions to log into Demosphere.
