Hrm. We just missed the WorldHostingDays:
"WHD.global is the largest hosting event worldwide with over 4,800 attendees in 2013 from all over the world."
http://www.worldhostingdays.com/
We should plan ahead for next year and go there, at least to distribute Torservers info material in front of the entrance. It's in Europa-Park, Rust, near Strasbourg: https://maps.google.com/maps?q=europa-park,rust
A ticket is 350€, too much for us if you ask me. Maybe we can find an ISP that gets free registration codes and doesn't use them?
