Mike Morford recently relaunched his Zodiac Killer discussion forum:
His forum was formerly available by invitation only, but is now open to everyone. It is filled with lively conversations on a wide variety of topics, including news, suspects, the killer’s correspondences, evidence, analysis, theories, and non-Zodiac crimes. My favorite topics, of course, are the cipher-related ones, in which forum members present their ideas, observations, and theories about the various cryptograms attributed to the killer.
