Quake Sourcecode Mailing List
From Quake Wiki
The Quake Sourcecode Mailing List (QSML) is an abandoned mailing list dedicated to the open source code releases of Quake and Quake tools. It was created and maintained by Maddes[1]. It is hosted at Yahoo! Groups[2]. An FAQ is available at http://www.inside3d.com/qip/text/qsmlfaq.txt or received by mail if you subscribe.
There is no known complete archive of the posts. The Wayback Machine only managed to save a few at http://web.archive.org/web/*/http://www.escribe.com/software/quakesource/* .
