Any con whose number is not in boldface is one I did not attend. I did attend the second (Boston MA, 1989) motss.con, but no con.report is available.
I was on the planning committees for both the 1996 Chicago con (ix) and the 2013 Ann Arbor con (xxvi).
Also, the soc.motss anthology contains some historical postings (dating back to 1989) that at least someone has thought worthy of note. This includes the motss.con Reports page.
