I was waiting for you to say that! (I've heard you don't like ENUM!)

Well, you get what you pay for, and this book is far from advanced. But for a newbie like me, it is a good way to get up to speed on PHP and MySQL.
Once I get the author's code working, I'll go create my own site/code from scratch and try to learn from things like this.
