Damn it dudes, I have a grade in webbdesign, I know that frames are good! They are userfriendly and can sometimes be good for the loading time but that's mostly for the 56k dudes...Well, your teacher should be fired since he obviously does not know what the web is about. Semantic HTML is must in today's web design. Ergo, you suck, gb2 internet explorer.
I'd wager you'd say "Dreamweaver is a great tool for developing websites" too, eh?
