The authors' experiences with electronic bulletin boards are recounted. Begun in 1986, the Physics Forum bulletin board for Massachusetts high school physics teachers spent its first few years as a resource of limited use only. In 1989, however, the National Science Foundation awarded the Five Colleges/Western Massachusetts Partnership a grant which facilitated the transformation of the Physics Forum to the SpaceMet network, which features electronic mail capabilities along with downloadable files and a searchable database. Another development has been the UMassK12 Internet bulletin board for Massachusetts K-12 educators and students. Issues and details about connectivity are discussed in light of the fact the UMassK12 can support 100 concurrent modem callers and that usage is increasing. Several examples of bulletin board messages are provided. (BEW)
