I just wanted to say "Thank you!" for writing such wonderful materials to help in studying. You have a special way of writing that really makes it easy to understand and learn. I use your books in conjunction with other Cisco materials and I have to say there's just something different about your writing style that I can't find anywhere else. So thank you very much, and I hope you keep writing for other certification exams as well!
