This study aimed to catalog the nature of written message exchanges on a network computer bulletin board, HSJOURN, which caters mainly to high school journalism teachers and publications advisers. The study analyzed the content of messages between December 1993 and January 1995 and cataloged them in the following categories: announcements; chatting; does anybody know?; ethical matters; conducting conferences; editorial guidance; consumer information; legal matters; trading classroom material; expression of opinion; reprints from mass media; sharing problems or solutions; sharing teacher tips; maintenance; and other. A tabulation of the number of messages falling into each category shows that most message activity occurred in 3 categories: announcements, chats, and does anybody know? Another tabulation shows that October was the most active month on the bulletin board and August was the least active. Activity was fairly consistent over the 7 days of the week. Other tables show: (1) the frequency of messages by classification of poster; (2) the classification of original message leavers versus those who reply; and (3) the frequency of messages posted by individuals. The research did not intend to provide statistically significant analysis but rather to serve as a descriptive snapshot of activity on this bulletin board at a particular time for purposes of later comparison and research.
