Everyone will need to register with a new account this season. Once your account is set up, you'll be able to renew players in future seasons.
If volunteering, (thank you) select the division for which you'll be coaching or assistant coaching. If you are volunteering for a generic cross divisional role (field setup, referee, photo day help), volunteer for the highest division that is relevant to you.
Also, unfortunately when you volunteer for multiple roles (ex coaching two teams), you need to complete the volunteer informaton twice. This is clunky. Blue Sombrero is aware of it and hope to change it in the future.
