Everyone who shares a list can share the list with their contacts.
So – if you share a list with Zelda, Zelda can share the list with her own contact Ganon. If you’re not already connected with Ganon, you two will become contacts. The more the merrier!
You can find all your contacts in your Contact List. When signed in, click on your username in the upper right corner, click ‘Friends’ in the drop-down.
