In the “Add Team” page, add “Name”(1) for the team, select (2) “Home Club” (optional). As a creator of the team, you can “Add players” (3), but this is optional. If you want, you can only add the team/team-name and then “Save” (4). The team will be added to that class and players will see that team as an option when they click “join” on “Team class” later on.
