Slack is a group communications tool that is used by a growing number of organizations including work places, sports teams, non-profits and general enthusiasts. It is now the primary way referees and assignors communicate.

All referees receive an email invitation to join our slack team. If you misplace the invitation, please email the assignor at and a new invitation will be sent to you.

One of the nice things about Slack is that you can access it in so many ways. There are apps for Mac and Windows. There are apps for iPhone and Android. Finally, there is a web interface. It’s your choice. All we ask is that you check in at least once per day during the season.
