Abstract: A computer-implemented method of introducing users of a service includes sending a suggestion to a first user of a service and suggesting an introduction of a second user to a third user of the service. The second and third users are both identified as contacts of the first user in a contact list of the first user and the second and third users satisfy predefined selection criteria with respect to shared contacts, comprising users identified in contact lists of both the second and third users. The method also includes receiving, from the first user, a response to the suggestion; and upon receiving a positive response to the suggestion from the first user, sending the introduction to at least one of the second and third users.
