Before I begin, and without picking on anyone specific, I want to say that it is generally unhelpful to say that because I, or others, do not know how the engine is set up that it is impossible to make any meaningful contributions to the list or on this issue specifically. My clients don't understand HTML. If I told them they needed to study how HTML works before trying to give me input on the sites I'm building for them I'd likely be fired. As a theater major I know quite a bit more than most of the people on this list about what makes a good play or movie actually work, but I don't pretend that knowledge is prerequisite to knowing if a play or movie is good. It either works, or it doesn't.
