Teams are a way to group users based on department, location, franchise, or anything else you'd like. Users with the manager permission will have oversight of the members on their team, so no more filtering through users to find your teammates. Users and managers can be a part of multiple teams.
To add a new team go to Users > Invite New User > Single User. You will see Teams at the bottom of this pop-up with the option to Add/Edit a Team. Enter your new Team name and click save.
To delete a team, simply navigate to the Add/Edit Teams option and click the X next to the team name you would like to delete.
