If you would like to add an email address of a family member or friend so that they will receive the same email updates that you do for your son or daughter, that person will need to be added as a guardian to your account. You can learn how to add guardian's to your account here: As a player/guardian, how do I add a guardian to my account?
Please note: Guardians do not have their own log in or access to any of the information in your account, you can simply add their contact information for notification purposes.
