He took up criticizing antievolution claims in letters to the editors of newspapers and in online forums. His stance in these matters has been one of theistic evolution, with the concern that science be taught in science classes, and non-science be taught elsewhere. He participated in Fidonet echoes, particularly the Science Echo, from 1988 to 1994. In 1989, he began operating his own BBS, first as an RBBS-Net node and later as a Fidonet node. He started the Neural-Net Echo in 1989, and the Evolution Echo in 1991. He became a participant in the Usenet talk.origins newsgroup in 1991. By 1995, he had contributed a FAQ on punctuated equilibria to the TalkOrigins Archive, as well as the Jargon and Biographica compilations. He also created his own set of web pages dealing with scientific creationism in 1995.
