I had a look through quite a few of these, and they all seem to be fixed now. Also quite a few of the things mentioned are opinions. There were also a few instances where I noticed w3fools was wrong.

Anyway, I see why w3fools decided to remove the list of now-fixed "errors". Thanks for wasting 15 minutes of my time - I'll bill you later :)

PS, your website fails w3c validation.
