Sorry for not clarifying this cygan: except for exceptions such as the case in which the main translator is not active anymore, we all agreed when we created the Alliance that the final word about accepting a back-up translator is his/hers (main's). According to this rule, in the case of German, we have to give Buchi-88 the opportunity to share his opinion and decide, because it will be with him that you will have to coordinate.
I'm already active here, just not in the thread every day (although I have less time to translate at the moment because of my job), and if I see that @cygan or @miau are doing the translations, or want to do them because they have more time or it just suits them, I have no problem with that - both members are absolutely trustworthy. That's why I don't interfere, but I also don't have a problem if one of them wants to do the main translation and I step back as a backup. But cygan or miau would have to comment on that.
In my opinion we are a very good community with a lot of cohesion on the German board, so none of us have a problem if someone else does the translation, the most important thing is the community and especially beginners get something out of it on the Bitcointalk board.
