"Take the GCHQ challenge! A message has been broken into 5 parts, each containing 5 characters. These parts have been disguised or hidden in different ways on this Web site. Simply find them, work out what they mean, and put them together in the right order. Then you will see our message!
You don't have to solve the puzzle to apply successfully to join GCHQ but if you include the message in your application form, we would certainly be very interested in talking to you."
I could only find these three :-)
