And on another thread...you wondered about the stairway to the roof? Well, there are a few, but that stairway is two things... it is an exit from the grand portrait gallery... door to the left as you leave the gallery to dumbledore's office. It goes down to exit the building backstage behind the JP bathrooms but it also goes up to the roof. If there is a fire, please don't go UP.
Ha! I was right, it IS a fire escape.
About the contracts, I believe they were included in some very early press releases, but I'm not sure. It dose sound like one of JKR's conditions though.
And yeah, the slow down on here was quite dramatic. It seemed to put a lot of people off.
