PROBLEM TO BE SOLVED: To establish invitation automatically at time point when a user registers and starts to use an application.SOLUTION: A server device 1 has a contact address DB12 which stores a contact address of an introducer candidate of a user who has registered already in association with the user and stores a contact address of an introducer candidate who is not associated with the registered user. When an application is installed to a user terminal, a contact address acquisition part 110 acquires a list of contact addresses including other user and his/her contact address stored in the terminal, and a contact address retrieval part 13 retrieves whether the user included in the acquired list of contact addresses is stored as the introducer candidate in the contact address DB12 or not. When the user is stored, an introducer candidate list creation/introducer specification part 14 creates an introducer candidate list and then provides the list to the user terminal, associates the introducer selected from the list by the user with the user and then stores the introducer in the contact address DB12. A compensating management part 16 adds introduction compensation to the introducer specified by selection. |
