The server computer where many client computers can post articles and read the articles posted from other client computers, manages the coordinate data of the icons respectively disposed at the client computers according to the respective intentions of the articles and reproduces the icons on the display screen of a client computer, at the respective disposed positions so that a user at the client computer can instantly understand the intentions of the posted articles without reading the contents thereof.Other References
