This may have been discussed elsewhere as it seems too obvious to me but I haven't come across it yet so thought I'd put it down for potential discussion.
Our background - We are only hosts and have mixed experiences that is mainly positive in hosting over the approx 3 years of hosting. But what is consistent is most guests don't fill out a response, some only want to communicate by SMS and some partner with other Warmshowers members and don't become a member themselves.
What I would like to see is a formal way someone can negotiate their stay. This way there is an electronic trail of the request which could trigger events.
What about if a request form has to be filled in for each stay, the host replies to the form and as the date is recorded, the host could receive an email just preceding the stay as a reminder. After the stay the form isn't complete till both parties have filled out an automated response send to the recipients and if this doesn't occur a message is sent at later dates. It could even be that after a given time the guest cannot create another request till the form is complete.
There are many other possibilities and benefits Eg This way the site Administration will know actual numbers of who is accommodated. And of course this is how commercial sites like AirBnB do business so not out of the ordinary except this is volunteer driven.
Am I off track here? What do you think?
