When you send an invitation to someone who is not a member asking them to join your traveler network, they receive an e-mail inviting them to connect with you on TripAdvisor. If they accept your invitation and join TripAdvisor, you will see them in your traveler network. If they don't accept or decline your invitation, we'll send them a follow-up reminder one week later. We won't send your friends any other e-mails.
