Beginners Drupal CookBook

A customization handbook for Drupal beginners. Drupal seems to be popular among UC departmental web developers: at least there is a lot of talk about it. I never liked that their slogan is "You don't have to know how to program (especially in PHP) to use Drupal". I like to program and to learn all about programming. But this would make a good reference for anyone wanting to learn all about Drupal.
