All teams will have a chat created for them that allows the coach(you) to send messages to them as needed. This chat will be sent to all members of that team.

You have the option to determine if all players and parents are able to post in the team chats for your teams. This is something that can be configured by clicking the gear at the top right.

Parents will be able to start a chat directly with you as needed and you can do the same.

Admins only will be able to post in the Club chat area and all coaches that are a part of that club or group will be able to post in the Coaches chat.
