Book Reviews
Signaling System #7 has been a tremendous success over the last few years, thanks to the many readers who have purchased this book. I hear from readers all over the world on a regular basis, and have the opportunity to meet many of you in person. I am always eager to hear comments from my readers, and appreciate the feedback and suggestions you provide. As an author, I discovered long ago that you will never satisfy everyone. Reading some of the reviews here on Amazon leaves me a bit confused however. This is the first I have heard these complaints, and based on the thousands of phone calls, letters, and e-mails I have received regarding this book already, some of these reviews do not match what we have heard directly from readers. Seeing as how these are anonymous, I am left wondering about the legitimacy of some of these reviews. I would welcome these readers to contact me via e-mail and provide suggestions on improvements for the next edition. If you have comments about any of my books, and suggestions on how they can be improved, please feel free to e-mail me at the address below. As many of my readers have already discovered, I always welcome comments and suggestions and enjoy hearing from readers.
