38C3 is over. Sadly. We hope that your journey home went well and that you had a good return to reality.

But many other things can be! That is why we want to ask for your feedback. Let us know what you liked, but also what you didn’t like. We appreciate both praise and constructive suggestions for improvement! But you need to be …

Our Chaos Communication Congress is a large, international event with many participants, including thousands of volunteers. This creates a lot of potential to experience social overload, health emergencies or threatening situations. We all know the feeling of searching for orientation and connection in the huge, overwhelming congress world with thousands of large and small projects, with concerts, discussions, lectures, full of art and culture. We understand that it can be a challenge to enjoy this freedom under the impression of all these people who, at first glance, are just as twisted, …
