Share a Pin, board or profile with your friends on Pinterest.
When you go to share a Pin or send a message on Pinterest, we'll suggest a selection of contacts for you, made up of people you’ve already interacted with on Pinterest. If you've shared your phone address book or Facebook friends list with us, we'll also suggest people on those lists who are known to be on Pinterest. We don't use this information for any other purpose than to connect you with your contacts.
