The idea of Chaos Post it is that visitors write messages to other visitors at this or other (also future) Chaos events via postcards. These are then stamped by the Chaos Post (with the respective event stamp) and then delivered by so-called chaos carriers. Any event visitor is welcome to be a chaos carrier and deliver cards. This gives them the opportunity to get to know the event from a new perspective and meet nice people, because usually you can only reach your destination by asking around. The delivery takes place according to the mission Statement: Delivery at the speed of Chaos!
