World's most polite Web form
I've seen forms that verify my entries on a form in real time but it's nice to see a 'Thank You' nonetheless. Contrast that with more confusing Web sites (Equifax, you would be a great example of this) or sites that can't do the basics (like let me know which one is inaccurate - user name or password) and seeing something that works well is refreshing. AND the page even autoscrolls down after I've completed a field. Excellent experience all around.
