Is one of your favorite shows heading for possible cancellation? Do you want to put a stop to it? Fan campaigns have been known to change TV line-ups in the past (most notably Star Trek), so why not now? E! Online is offering very detailed instructions for fans who want to save Better Off Ted, Chuck, Life Unexpected, One Tree Hill or Parenthood.

E! Online, E! News and Daily 10 will give fan messages directly to network heads, so if you want to save your favorite show, take to Twitter and start making things happen. (Make sure to use the hash tag #SOS plus the show’s full name in your tweets.)
