Voluntary contribution

Experience the joy of giving!

This web location contains a huge amount of material, most of which is free. The focus is on quality, accessibility, factual correctness, and honest presentation in a clear layout, rather than on seduction and deceit. Also, no intrusive advertisements, cookies, or search engine analytics are implemented, let alone any slow-loading server-sided database-driven rubbish. On the rest of the Internet one can see how rare and valuable this is. If desired one can express one's appreciation through a financial contribution; the below PayPal button allows one enter the amount of one's choice. Or one can use one of these alternative methods of payment.
