Any group on Count.It with a PRO subscription can create Teams. Teams are sub-unit of the group, and the number of teams and size are entirely at the discretion of the PRO Admin. Team preferences can be set on the PRO Admin --> Teams page.
Admins can allow users to create teams and join teams, or they can restrict those privileges. If restricted, Admins are then responsible for assigning new members a Team once they are actively registered to the group. If allowed, the system prompts all new users to join a team if their group has Teams set up.
