USPTO's website is http://www.uspto.gov.
Guess what happens when you go to http://uspto.gov. If you guessed "The page cannot be displayed," give yourself 10 points. If you've ever typed in uspto.gov and received the same error before, give yourself and additional 10 points.
I'm not really sure what it is called..."domain mapping" maybe, but I'm pretty sure its an easy thing to fix. (maybe someone will leave a comment explaining how to fix it)
