Hi, I just wanted to answer your remark on SemanticMarkup. I think that including the complete file, or showing where exactly to insert your changes would be a great idea; see my comment on the page itself. And by the way, very nice idea indeed :-)

Ian, you might want to take a look at http://wikka.jsnx.com/SmartyPants - for a different approach to embedding SmartyPants into Wikka (as an afterburner, not as a preformatter).
