iam from germany. send my a pm with the text you dont understand - i will translate it.
i looked at the rules on that page. and your page MUST be in german. so i think you can forget about this.
i saw the discussion about the german law. yes its very strict when it goes to protecting childrens, but only when your webspace is located in germany.
you as a person living in the us. or australia? with a server located in your country dont have to fear the german law. it only effects content which is on servers located in germany.
