The Age-group lead coaches have the "Commissioner" role in teamsnap for a specific division.  It allows you to add players and modify rosters, as well as assign team managers.

The first thing you will want to do is add yourself as a team manager for the teams that you coach directly:  [[add division commissioner as a team manager]]

Secondly, you will want to [[add assistant coaches and non-commissioner coaches as team managers]]

Finally, you or the team's head coach should review the roster and [[invite the team to join TeamSnap]]

Returning Commissioners should [[archive old teams before inviting players]]

Commissioners have the ability to [[https://youtu.be/by74savrrz0|move players between rosters]]

To put a player on more than one roster (eg, as a guest) Commisioners can find the player in the "Members" tab, then select "Actions->Copy Profile" for the player.  This copies the player onto a second team.  For players that rarely act as guests, it's better to just manage their attendance via email.
