This is a way to say thanks to the author of this site.
All the programs and information in this site are given free of charge. Some of these programs took me more than one year to complete, so I would be happy if you want to contribute some money. This will also serve to pay the Web hosting (about US$ 100 a year).
So, if you want to send some money to me through Paypal, please click on one of the following buttons. It is very easy and secure.
Thanks a lot.
