OK so I will try to keep a list of the ARG URL's the side URL's and the hoax URL's here.
Painting hub: (paul scheer blog gone)
http://roniemidfewarts.com/i/ (redirect to dcpb now)
Lost University (ARG status unknown)
I am not currently tracking sidelinks, ie paul scheers blog, bananasplit, bpm, foolsgold, and so on. Currently I believe that they will serve their purpose and leave the ARG once their role is complete.
