Wait. You haven't listened to the MousePods?
Seriously, though. I've been putting together a wiki for the historical stuff. The reason I went with wiki, is I think it's something that will never be finished. Something that I can keep developing...and adding to.
I would be delighted to join forces and design an über Disney park wiki that would encompass both history and current info/tips. Basically, designing the structure is the hard part. Once it's up, we just give the "edit" password to our favorite geeks and it will grow by itself.
...but if you'd rather fly solo, I respect that, too. Either way, you have my support.
(I was gonna PM you with this, but I'd love feedback from the Loungers, too)
