Wow, this looks really incredible.

Have you added the PHP code snippet to all pages on your site so you can track every page, or did you just selectively choose certain pages?

The only thing that's a little daunting is changing the .html to .php on each of my site pages, and then making sure that all the links within the site correctly update so they point to the .php pages... seems, even with Dreamweaver's search and replace, I manage to miss links whenever I do global updates.
