Sorry for jumping in here 
I'm danish - and i think that the only good reason i can find to start a new language area is if there's quite a lot of Arduino users speaking that language AND they are not very fluent in english.
Usually most people from the scandinavian countries speak / read / write english pretty well.
If we have too many different language areas the information in the forum will be fragmented, and we run the risk that some information is only available in one language.
