Thanks for the reply.
Printing Form would be basically an acknowledgement of the "House Rules" with regard to my location. Nothing to fill in. There are already there.
Maybe someday there could be the option of including a personal requirement which needs to be checked before being able to proceed booking. Its like the little "click" asking a user to have read the "Rules & Regulation" as in any purchase.
I am aware not many people read them or care but at least its there. And then every host can decide on their cost&balance analysis between making it easier or more difficult for guests to book their property.
I would care so much about a signed pledge if I offer a listing in Berlin or London , although it matters. But being in a nature environment might be a different incentive for guests to comply.
Just talked to another client who searched 4 hourse before deciding on an airbnb in my location. So people take the time to find the best fit.
