I am co-organizing the THATCamp New England 2017. We’re just about ready to start taking reservations. Unfortunately, we’re not in a position to offer t-shirts or host children. We’ve managed to make this Camp free of charge, and provide breakfast and coffee, in part because my co-organizer’s institution has been very generous. They’re not insured for children, though. And we don’t have the capital to pre-order shirts. Is there any way to edit these features out of the registration form? I see the forms on GitHub, but it doesn’t look like there’s an option to edit the form on THAT Camp sites.
