When I was a host early on you could actually speak with a potential guest thru airbnb. It was indicted that it was a monitored line and the guest knew you were calling thru the site. I was able to "vet" a guest much more easily and answer any additional questions that they had by being able to actually speak to them. I don't know why you discontinued this service.
As someone who actually lives at their rental and who leaves to stay elsewhere when I have a guest, I would appreciate having this service again. I think that it helps to make me more comfortable with the potential guest and clears up any and all questions prior to accepting or declining a booking.
