After some discussion in house, we have come to the conclusion that although such a book is greatly needed, it doesn't actually exist in a single unified form. So...we're gonna write it. The basic approach will be along the lines of "Teach Yourself to Do-more in 21 Days". It will be a more task-centric approach to covering the material, with emphasis on doing small tasks and building on them, while touching on the key training points.
So...for all of you who have or are developing Do-more projects...please help us by telling us what was most confusing. We want to make sure that we hit those things most thoroughly. Please don't be shy...
