Please do feel free to read these papers, send the URLs to your friends, print them out, copy them for your friends, or in any other way, make use of them to help you and others learn something.
If you are a teacher, feel free to print them out and distribute them to your class. I'd love it if you could let me know (KenFe@HotMail.com) you have done so, just so I'll know that somebody out there is reading this stuff.
In general, I would just love for as many people as possible to see my little papers, read them, and get some use out of them. I don't do this for a living, and I'm not looking to make money off it. The one thing I would like, just for ego satisfaction, is that if you do make use of these in any ways, let me know...just send me some email, so I know that somebody out there is getting some benefit.
The only caveat is, if you are looking at making money off of these—for instance, if you are publishing a book and would like to include some of this material—I do not give you permission. Yet. Please contact me first, and we'll talk about it.
