I mean, that on https://glotpress.simple-press.com/glotpress/projects/simple-press-core/version-62/sp/de/default/ there are several empty translations which I’ve done in the file I added here in the forum, but since I’ve added the file here in the forum, it was possible to update these language files in the forum, so I don’t know, if the version which is now in my forum is the version I did or the version, which is shown at the link. Also there are many yellow translations, so it seems to be in working state.
I would like to help you voluntarily (my german is not so bad as my english 😉 ). If the way via an account is easier or more direct, I prefer that….
