Contact Information

Don't hesitate to contact me regarding any question related with my books.

Moreover you are encouraged to contact! If you'll tell something of significant usefulness (e.g. an error correction in a book, additional materials, or just your opinion about a book) you are likely to receive gratis license of a E-book or a book as a bonus.

So please tell to the author what you think about the books as a reader. This will help to improve the quality of the books!

Please contact the chief of the mission by email: Victor Porton <porton@ex-code.com>
