Basically, it's a forum for retailers and exhibitors to share their offers that they'd have run at the show, but it's also going to form a platform for livestream and videos of some of the seminars that would have taken place.
As it stands I have no real clue as to the scope, I see Victoria Minis have put up their show model for order on the page, and I know Steamforged are planning to conduct their keynote speech online. But it seems like something people might appreciate being told about.
