eBook Topics - Your chance to provide input

We're considering creating a free eBook on Microsoft Access. Yes, in part a selfish way to create awareness about our products. But equally important, as a way to help the many Access users that find the phone-book sized "how-to" guides available at bookstores too expensive and too unwieldy. We've got a general theme already, but this is your chance to weigh in. What would you want to see in a free resource for Microsoft Access? What are the questions you have about how to create really powerful Access databases?
