I am new to wordpress, mysql, php and themes. Your visual anatomy clears up some of the problems I have had so far. For instance, I didn't realize that the html tag started on the header page, skipped the index/content page, and other pages entirely and ended on the footer page. You have no idea how much grief that tidbit saved me. That kind of information may have been sitting somewhere on the codex site, but I didn't run into it after several days of grazing for info.
My problems usually arise over simple things, things that are just too obvious to be explained by the experienced.
