Halo Easter Egg - Message

I was browsing the site and decided to contribute something I found a while back.

On the map Timberland there is an unintentional flaw where you can get up to the top of the map. You will need to reverse a ghost to the top of the slope and your friend to blow your ghost further into the invisible wall so you pop out on the other side. Apart from being almost invicible up there you can run round the whole map. In one corner is the level designers name and date of creation and a few other details. (These are spelt out in Explosions, you can'y miss them.) Directly On the otherside of the map is a message I will let you find yourself...
