UPDATE 12-31-2014 SERVER IS OFFLINE, IF YOU WOULD LIKE TO CONTINUE THIS CHALLENGE PLEASE CONTACT ME VIA THE ANSWERS EMAIL ADDRESS
One of the readers suggested that I set up a place where readers can test out and try their hands at enumerating on a "authorized" site. Well, I have stood up a web server, and there are roughly 22 pages that are enumerable using one method or another.
Good luck!

UPDATE: Each discovered page contains a hash, it's simply a way to verify you have found something that was intended to be found. You can submit them as well or just shoot over the URL of the pages you found.
Please send in your answers or ask questions, this isn't a secret or CTF, this is here for you to learn.
