There is no charge for any information or service on this site. There are no ads. This will not change.

However, if you wish to make a monetary donation (of any amount), it will be gratefully accepted. Whether as an act of support, an appreciation, or simply a gift, I thank you for it in advance.

I maintain this site because I love it. It has never been intended to be commercial. As long as I have a working phone line for my modem and electricity to power the computer, I suspect it will be here. I am fortunate to have one of the finest commercial-grade Web hosts that exists. I hope you find the site to be interesting and helpful. Occasionally, site visitors ask how they may lend financial support in appreciation for this service. I am willing to accept your gifts, with warm thanks.
