The partially php-ized site is here:

To reiterate – homework for next time is:

make your site dynamic (has common “wrapper” (index.php), can switch between pages; has functional logged in/logged out states)
also, improve the UI further

and ask questions here, or in person, or via email, or via facebook, or whereever.

Aim is to get your application into a state where it’s perfectly usable, only without actually showing or saving real data (that will come later).
