Nobody is LARPing an Eingetragener Verein, they're just being one, and the law requires them to have a board and presidium.

As they got hundreds of votes on the issue, that means tens of thousands of euros in membership contributions. It doesn't seem unreasonable to want to create a legal entity for that, and an e.V. is easier to set up in the beginning (although it can lead to a lot of drama later).

Sort of yeah! I got used to it by now. At the local hackerspace we have a voorzitter, penningmeester, and secretaris -> president, treasurer, and secretary I think would be the English terms. All sounding fancy and together they're the board. But they don't dress up or anything, it's just terms that are commonplace for small organisations here, in Germany (like with Codeberg) as in the Netherlands (like our hackerspace). In practice people just do as they see fit, the titles are often just a formality and not taken seriously unless you can use it to teasingly redirect work onto another person :)

I think German non profit organizations are required by law to have a certain level of governance structure.

Guess the Germans woke up and had a board meeting about this comment lmao
