Without the following people, this site wouldn't be as good as it is today. In chronological order:

Jim Grimwood : Details from the October and November 1986 issues, scan for issue 6, plus an honourable mention for doing some other cover scanning but being pipped at the post by someone else. Also typed up the odd article. Owner of the Your Spectrum Unofficial Archive.
Gerard Sweeney : Scans of all but a few YS covers, and also the Joystick Jugglers. Runs Hackers Anonymous.
Paul Jenkinson : For the currently ongoing generation of screenshots for almost every game mentioned in YS, and also for the entries for the final two issues. Maintains the Spectrum Hardware Index.
Martijn van der Heide : For allowing me to include search links to the World of Spectrum Archive, as well as storing the full-size cover scans, plus all the other scans, plus being a minor deity.
Martin Currey : Top Tens for the Nov'88 and May'89 issues.
Mark Green : Top Ten for Aug '88.
Fernando Brischetto : Scans for YS16 and YS29.
Christoph Idstein : Scans for issues 1, 3, 8, 9, 19, 20 and 28.
Selby Duffield : For selling me his copy of YS93.
Softy Nonowt : For allowing me to pinch the bulk of the text of the YS Complete Guides series from his website.
Matthew Carrier : For providing the material in the YS Memorabilia page.

My huge thanks go to all these people who have spent a lot of their own time contributing to this site.
