Celerity was among the many BBSes based on the Forum-PC BBS by Ken Duda.
Others include, Emulex, Emulex/2, Monarch, Oblivion, TCS, LSD, Baphomet, and a
few others.
Forum PC was written in Turbo Pascal and due to how the code was organized,
made for an excellent learning platform for TP coders. The problem was that a
certain segment of the population thought nothing of tweaking a few minor
things, renaming the software, and then calling it their own.
