I haven’t, but I also have the same idea. I think that it would be a great way of creating a place for people to meet and talk and support each other. I would probably create a Facebook or Meetup group first and take it from there. You can probably meet at your local library, most have meeting rooms you can use, or I’ve also considered hosting people in my home. I’d imagine there would only be a handful of people joining, at least to start.
