(I am Dutch, "high five")
How the... what the!!!
Ether i have a really big hangover, or I have dreamt that there was a topic about this.....
(I am not kidding!)
dutch is not German
And to answer your question:
There is a reason I have not made a dutch version.
Everyone I know, knows how to read English.
I can see how it might be good to translate it for the younger audience,
but think I can safely say that they would be able to read it in english as well
(despite there young age)
To say it more Basic:
Because English is like a secondary language in Holland, there is little reason to translate it to dutch.
However, do not let me stop you from make a dutch translation, I will even help you with it if you DO start it.
But in my opinion, it is not needed.
