Isn't there any german translation of membership/newsletter/buddypress?

Hi!
I'd just like to implement those plugins on my website... and found out that only membership has 1131 textmessages to translate.
It seems that it's me who has to invent the wheel once again... is there NO ONE who has already done some translation work? Nor a group of wpmudev users that could and would share the work to be done for a localization?
Please - any suggestion/help is very welcome.
Thanks!
