Before I put this page on the internet, I checked and made sure that every link worked.  By using the links, you agree not to hold me legally liable for any consequences resulting from their use or misuse.  This brings up two issues:

1)  Though I have tried to screen out the unscrupulous markets, I offer no guarantees about the accuracy or suitability of any site listed here.  In using these links, you assume any risk there is for using or misusing the information they contain.  All opinions expressed on the sites to which I have placed links are those of the sites' respective authors.  If the science behind some of the science sites isn't very good, so what?  That's one of the reasons why "science fiction" got its name.

2) Obviously, I can't spend my whole life keeping these links up to date.  If you find one that no longer works, or that has changed (when I tested these links for the web page, one of the test links had turned into a porno site--yech!), contact me by email at 413@nls.net and I'll fix it as quickly as I can.
