I am 70 years old, have used the `Dummie' and `Idiot' books, plus several more. Not having ANY experience with computers, up until 2 years ago, I go where I please and do what I want, thanks to the good books on the markey. This book, was the most expensive; but by far, the most helpful! (My wife thinks so too.)
I'm not a novice with the internet and this book does help with understanding the net and its ups and downs. I would recommend it to beginners and the more experienced net users who wish to create their own sites or just for interest.
