If you have created a registration event, you can set a maximum amount of members in a team. To add an individual to a team you must first check that the team has enough capacity to add another individual.
You can check the maximum capacity you have set up for teams in the event in the ‘registrations’ tab. Navigate to registration settings.
If you haven't created an event with registration you do not need to worry about team capacity.
You can add an individual to a group (team or family) by going to the 'Teams' tab. Find the group and click manage.
This will open the team pop up. Click add member
Insert the information required including email address, name and any questions that have been set by the event manager.
All individuals added to the team will be sent an email confirmation.
