Thank you for your contribution

Tip: Are you a non-native English speaker? I have just finished creating a Web App for people who enjoy learning by reading. Make sure to check it out; there's a lot of free content.

You have done more to keep this website running than 99.9% of its readers. If you would like to support me even more and get a lot of value in exchange, the best thing you can do is buy my books, and, of course, you are always welcome to contribute again.
