Eberhard Nuffer has been making newsletters (in German) for some time. Now we have some good news: They will become available online.
A post at off2 informs us that they will be made available. The first is already available, and the second will be added in mid February.
Also notice that off2 has an English section for those of us that don’t read German that easily.
Updates
2021-01-25: Added a line about the English section of Off2.
