Abstract: Disclosed is an electronic bulletin board system, which communicates with a user computer via a network, and mediates information exchange therebetween by an electronic bulletin board function. The electronic bulletin board is accompanied with a database of a notable words collection storing a plurality of words that are appropriately selected, each word in which is linked with a corresponding URL. A message text from a user computer is checked by using the notable words collection. When the message text does not include a notable word in the notable words collection, the message is posted on the bulletin board. When a notable word is found in the text, the notable word in the message text is converted into a hypertext format having the URL to which the word is linked as a link destination, and the message is posted on the bulletin board.

Abstract: A message desired to be posted on an electronic bulletin board sent from a user's computer is checked with a posting-prohibited word list and a heed-required word list. In the posting-prohibited word list, words previously selected as those inadequate to be posted are registered. In the heed-required list, words previously selected as those to be heeded about the social reaction even though the message is allowed to be posted are registered. When the message desired to be posted includes no posting-prohibited word, the message is posted on an electronic bulletin board. When the message includes any heed-required word, the posting of the message is reported to an operation manager computer. When the message includes any posting-prohibited word, a letter screen indicating that the message cannot be posted is sent to the user s computer which has sent the message, and the operation manager computer is informed of the rejection of the posting.
