In the ASCII table example (http://arduino.cc/en/Tutorial/ASCIITable), there is a broken link due to a typo (I guess). It is the reference to asciitable.com, with this URL "http://www.asciitable.com%20and%20http//en.wikipedia.org/wiki/ASCII".
I wish there was an easier way to report this sort of stuff.
Best regards,
