Just to let you know, I have download both de.po files for manual and website, installed Poedit, merged both with the newest .pot file and started continuing your work on the German translation. Since I'm a newby I hope that I understood correctly that this is the process to follow :-)
Do I need to check-out something to protect from overriding any work, or is this notice to the community sufficient?
If you're fine with this, I will submit the translated .po files to this list when done. I'm working on this on the train on my way to and from work, so it shouldn't take too long :-)
