Jeez, Cam, is this really your very most favoritest error in all the world? I've lost track of how many times I've seen you bring that one up. Do we get any points at all for fixing it in the PDF update?
It's a fact, our graphic designer can't spell. Whenever he adds a headline or title bar during the graphic design process we run the risk of that kind of thing. I once saw an entire chapter of a book with a header that said "Magic Itmes", which is way, way worse than one page that says "Foreward". Neither typo affected the usability of the product, thank goodness. It's the usability typos that keep me up at night.
