In version 1.0.1.0, the first posted to news.answers, I depended heavily on the kindness of the various MLMs' authors. Without their annotations and corrections it would have been a misleading document. Two people who were very patient with me were Eric Thomas (author of LISTSERV) and Stephen van den Berg (author of SmartList). Especially Stephen :-). Also, David Barr, author of the Majordomo FAQ, is the man who suggested I turn this document into a FAQ in the first place--I originally intended for it to be just a few paragraphs in his document, and somehow it ballooned ...
In version 1.1, most changes I made were to correct errors that various people spotted and pointed out to me. Specifically:
Bob Bagwill bagwill@sst.ncsl.nist.gov pointed out that SmartList's remote administration by mail requires placement of commands in the message header.
Brent Chapman Brent@GreatCircle.Com corrected my misapprehension that he was the author of Majordomo's link to ftpmail :-) while kindly taking the time to read over the FAQ as a sort of historical consultant.
Michelle Dick artemis@netcom.com has written several messages that changed my view of some issues (this goes back to the first version)---so I can't quite point to which section she changed, but her influence is in there.
Joe Sparrow jsparrow@uwm.uvic.ca was the first to point out to me that my discussion of MTA's and MUA's under VM was incorrect, and to give me a clear view of what the situation really is.
David W. Tamkin dattier@wwa.com caught my use of "priority" when I meant "precedence."
Windigo the Feral windigo@thepoint.com sent a very nice description of a particular type of built-in mailing list support, in DG/UX Sendmail.
Needless to say, I am responsible for all errors that remain.
