PROBLEM TO BE SOLVED: To efficiently conduct negotiation in a purchase and a sale of a commodity requiring negotiations. SOLUTION: Negotiation is carried out smoothly between a purchaser and a seller using an electronic bulletin board system on the Internet. A negotiation content in the past is easily grasped to carry out the negotiation smoothly in the system using an electronic bulletin board, since the purchaser and the seller are allowed to watch the content written in the past on one common page, differing from communication by an Internet electronic mail. |
