Completable Signup Form

This is a signup form we put on the homepage of Completable: a webapp we just launched to make the client approval process for your websites a breeze.

I wanted to have no labels, and instead, rely on the placeholders. So what I did was put in labels before all the elements. Then, I used JavaScript to check if the browser supports placeholders. If it does, I copy the label text into the input's placeholder and remove the label -- if not, I leave it alone.
