Now that I closed my account on couchsurfing. com, I lost pretty much all my contacts, and feedback (well, I still have it, but I need to parse some JSON file to get it, and I'm too lazy to do that).
So you have to trust me. Here is an old map of the first couchsurfers I hosted back in 2011/2012. I'm on BeWelcome.org and also on the new and promising platform named couchers.org. Some links still work. But don't waste your time with couchsurfing. com, this site is dead now.
