Before emailing me with questions, please look through the site index to find the information you are looking for. Many of your questions are likely to be answered somewhere on this site. I suggest that you also start at the FAQ page, found here.
Please keep in mind that I write this web site in my spare time, as a gift to the Web. I have minimal time to reply to email, so I will respond when I can make time to do so. In return for my effort, all I ask is to receive a “thank you”. :-)
