OiO Network: An off-ice officials community of practice

For the last three years we have provided off-ice officiating for the area NAHL team. They announced a few months ago they would be adding an NA3HL team in the Fall of this year.

We've been asked and agreed to provide scheduling for OiOs for the new team.

I know others of you also provide OiOs for multiple teams/leagues so I'm curious what you've learned? Tips you'd offer? Mistakes you made we should avoid?

Help much appreciated!
