Teams allow you to coordinate a group of people - a class, a group of friends, subscribers to your content, and so on. Using teams, you can add a large group of people to a discussion in one go, making it easier to manage Participant Rights and Roles.
Please note that teams are currently a restricted feature - users do not, by default, have the capacity to create new teams. Team names must currently be unique, and leaving this feature open risks team names being used up on inactive teams, to everyone’s detriment. If you wish to create a team, you will need to Contact Us, and we will be able to give your account the right to create a limited number of teams if appropriate.
