I've mentioned the theatreforum.com message board on this site and in messages. It used to be a discussion board on the whatsonstage website. The discussion board got moved off the main website nearly a year ago - and now has had some more interesting developments.
I don't know that BWW faces similar producer pressures - seemingly not - especially given the discussions on the main Broadway message board. I don't see the BWW message boards getting locked out from the internets or cloud. "Protected" from whom?
