The newsletter started in December 2014, first monthly and then, from summer 2019 on in a quarterly rhythm. The next newsletter for autumn (Herbst) 2019 showed that the character of the newsletter had changed. It was not any more just a hello with a short comment on the former four weeks. The newsletter now contained reflexions on the past few months and an outlook to events and projects in the following time of the year. In March 2021 there was another change: a pause. Thus there are no more links with invitations to subscribe to the newsletter.
