Q: Somebody just posted that Roman Polanski directed Star Wars.  What
   should I do?

A: Post the correct answer at once!  We can't have people go on
   believing that!  Very good of you to spot this.  You'll probably be
   the only one to make the correction, so post as soon as you can.  No
   time to lose, so certainly don't wait a day, or check to see if
   somebody else has made the correction.

   And it's not good enough to send the message by mail.  Since you're
   the only one who really knows that it was Francis Coppola, you have
   to inform the whole net right away!
