Sci.skeptic
From RationalWiki
sci.skeptic is the *first* forum newsgroup on the Interwebs to discuss matters on skepticism. A lot of the discussion focuses on "Sir Gilligan Horry" and his adventures. There is a lot of crap that leaks in, with instances of Ed Conrad, Thrinaxodon, Horry, and BroilJAB all crapping on the newsgroup with their utterly asinine crap. There is some non-spam discussions. And serves a lot like RationalWiki but back when UseNet was popular.
