The Family + Friends tab in your contacts allows you to link contacts to each other. To add a new family + friend, click on the CONTACTS icon and then the CONTACTS tab. From there, select a contact and click on the FAMILY + FRIENDS tab.
Click on NEW to add an entry. From here, enter the contact's family/friend's name, relationship, and contact information. You can also select to create this person as a new contact as well. This will automatically link the two contacts together.
After you've entered the information and clicked on CREATE NEW, click on the FAMILY + FRIENDS tab again to see the list of entries to this tab.
If you click back on the name of the Friends + Family entry, you can click on GO TO CONTACT to see Jane Smith's new contact entry.
From the Jane Smith contact's FAMILY + FRIENDS tab, you can see that "Shelby D" was automatically created as a Family + Friend entry in the Jane Smith entry.
