Mailing Lists and Newsgroups

techdiver mailing list, part of the Aquanaut site. Mailing list formed as a revolt against the uninformed debates of advanced diving in rec.scuba. Dedicated to technical diving, although it includes a lot of cavers.

Unfortunately in 1995 it was discovered by George M. Irvine III, who managed to be obnoxious, insulting, and egotistical in his first three posts.

George Irvine was even kicked out of TDI for his comments on techdiver about Rob Palmer's death.
This list certainly does not abide by RFC 1855: Netiquette Guidelines

Despite the high noise to signal ratio, it is a fantastic source of information, such as the recent Harness Rigging thread.

Randall C. Allen wrote some very useful notes on using techdiver, and on using scuba-l.
