The German translation seems to lack behind a bit. I can translate the missing parts for you if you want me to. Just tell me and I'll begin.

Well, I'm done. At least everything is translated now. Nevertheless I'm still a little bit unhappy with some things my predecessor did. I already tweaked some issues (made the translation more polite - e.g. "Sie" instead of "du"). I also corrected some typos, but still here's work left to be done. But for now, I guess, this version is quite usable.
Ah, yeah, before I forget: If you know projects still in need of a (hopefully good :-) ) English-German (both ways) translator, please let me know.

I have updated the German traslation and also corrected some spelling mistakes from the previous version.

/EDIT
I noticed that some parts of the program's text is hardcoded into the app like the "Toggle edited stats" button or the achievements' texts. Would it be too much work to make them editable by the language file? Alternatively I could directly edit the sourcecode (if you'd send it to me^^) but with the unpleasent implication of having two seperate versions.
And btw if you need more coders I'd be happy to help you if I can. For example I've worked a lot with Perl and regular expressions lately.

To make suggestions i'd like to know what you're currently up to, what you are planning and where you have problems right now. :) Also, as I have some experience with regular expresions I can try to create some bits of "prefabs" if this would be helpful.

Updated.
