Here's how you invite a new family member to your family account
Go to Settings
Select Family Settings
Select Send e-mail
Enter the person's information and click Send
The recipient will receive an email to confirm the invitation. Upon accepting an invitation, the user can:
Create a new user
Log in with an existing user
When a new user is added to the family account, the user will become a family member of that family account.
If an existing user is added to the family account, their existing subscription will be replaced with the family subscription. All the files will remain unchanged on the user as before.
The family account is handled by the person who sent the invitation.
