Hey Ansgar,
Just ran the German disclaimer through Google translate and it gave me this back:
Despite careful control of the content, I assume no liability for the content of external links. The operators of the linked pages are solely responsible for their content.
What you have there is rather confusing. After a few reads one might guess the true meaning, but I think that for such a legal kinda thing, it should be as clear as possible.
I apologise in advance if I'm committing a faux pas in mentioning this.
Cheers,
Gus
