Well... I am happy to say, that this is just not true. We do validate our pages. That is the first thing I do after writing a tutorial is to validate the pages. (Test us in W3C's XHTML validator) ... And if we forget to validate, our faithfull fans let us know with an e-mail :)As for frames, we have talked alot about re-designing the site. But the bottom line is that the current layout works great for us at this time, and we want to focus on writing more tutorials.And also... W3Schools.com is NOT the same as W3C...
