Election-methods mailing list
The venerable GNU Mailman-based mailing list started in 1996 (before GNU Mailman!)
The election-methods mailing list can be found at:
The list is for discussion of the nitty-gritty details of single-winner election reform, the relative merits of different proportional representation systems, and the technical underpinnings of all election methods. "election-methods-list" discussions tend to be technical in nature (or at least, very laden with jargon), with the ultimate goal of providing recommendations and educational material to the electoral reform movement.
The list was started in 1996 by Rob Lanphier (User:RobLa on this wiki). During its first few years, it was on eskimo.com, but moved to electorama.com (hosted on Dreamhost) in 2003. The list has been continuously active for 23 years.
