Many thanks to Bill Wohler <wohler@newt.com> who meticulously read,
commented, and constructively criticized an early draft of this.
Also, thanks to Bill for being a role model for me both as an FAQ
maintainer and as a supporter of free information on and off the
Internet.

Thanks to all the nn enthusiasts in news.software.nn, especially Milt
Epstein <epstein@napcc-hp.cvm.uiuc.edu> and Sven Guckes
<guckes@inf.fu-berlin.de> who have posted and/or mailed me lots of
good tips over the years.  And thanks to my brother, Tom McGough, who
performed the tedious task of counting the nn variables!

I wrote most of this article while I was visiting the great Lone Star
State of Texas.  Thanks to my friends Matt Kaufmann
<kaufmann@cli.com>, Holly Bell <hbell@mail.utexas.edu>, and their cat
Baby Kitty for putting me up in their home and letting me tie up
their phone line while I was working on this.  Thanks also to
TexasNet <info@texas.net>, Real/Time Systems <info@bga.com>, and
Computational Logic, Inc., who all helped me connect to the Net in
Texas.

Thanks also to all my regular providers, Best Communications
<info@best.com>, Northwest Nexus <info@halcyon.com>, Jazzie Systems
<info@jazzie.com>, who let me use lots of their space to make
information available on the Net.

And, as always, I want to give special thanks to Thomas A. Fine
<fine@cis.ohio-state.edu> for setting up and maintaining the
hypertext archive of FAQs, which, to me, is one of the greatest
things on the whole Internet!

Please let me know if I've left you, or anyone else, out of these
acknowledgements.
