USER MANAGEMENT SYSTEM, USER MANAGEMENT METHOD, INFORMATION RECORDING MEDIUM AND USER MANAGEMENT PROGRAM

摘要

In order to properly send a notice for encouraging a user who has not attempted a login for a long time to login in a network communication game or an SNS, a terminal device (251) of a user management system (201) stores friend user names and reports a login user name and a friend user name to a management server device (231) at the login time. The management server device (231) manages to make the last received report correspond to the login time for every transmitting source user name. If a login user name is designated as a friend user in a past report of a friend user name designated in a new report, the management server device notices the terminal device (251) of a login time of the friend user name in the new report. If a difference between the login time of the fiend user and the present time is over a predetermined threshold period, the terminal device (251) transmits a login encouraging electronic mail to the mail address of the friend user managed by the terminal device (251).
