This week's sponsor is Wiley, publishers of the Dummies series. My wife Sara has a small love affair with the Dummies books. As I look around our office I can see at least a half-dozen on subjects ranging from personal finance to gardening to taxidermy. Well, perhaps I exaggerate, but these useful yellow books do make the world go around. Click on their ad to find about their Dummies Month promotion, and maybe win a free prize!
