I will be happy to provide permission to have specific postings published in non-profit newsletters and such as long as I am asked, when ever possible. In return, you must list the author, source, and copyright, and send me a copy of that newsletter. My material may not be copied or published without attribution. Republishing or using postings and articles for commercial or other purposes without permission is a violation of various copyrights, and is generally frowned upon. If you want to use something for commercial purposes, we'll talk. This also applies to using things on a web page- and it is preferable to just provide a link to the original source, rather than copying the article.
You can easily contact me via E-mail [ rwg@autox.team.net], US Post, or telephone.
If you're interested, here's a good introduction on copyrights, what they are, and what they cover.
