[Helge Kreutzmann]
Did you have a chance to review my question (or should I explain more the project?) or is there another list which I should approach?
I believe you have reached the only relevant list for this topic, and the lack of response is simply that no-one has been able to give priority to this translation. It is the reason I did not reply, at least.
Is it possible to contribute to the manpages-l10n project using a web based translation editor like Weblate or Transifex?
