<P>PROBLEM TO BE SOLVED: To prevent users who don't yet fully understand contents of services from subscribing. <P>SOLUTION: A plurality of display screens to present the contents of services thereon are classified into first and second display screens. A display element for sending a subscription request from a user client to the server is arranged on the first display screen. When the display screen sent in response to a browsing request from the user client is the first display screen, information on the description of a page where a display element for sending a subscription request from the user client to the server is arranged on the screen presenting the contents of the services is sent to the user client. Thus, because the display urging the user to subscribe is provided only on the first screen where the user is supposed to have understood the contents of the services, the user can be prevented from subscribing without fully understanding the contents of the services. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
