No more like two official ways of spelling. Nynorsk and Bokmaal. At least that's what Kay ment I think. Couldn't recognise his Norwegian as Nynorsk though :-). (Nynorsk is more popular way up North I think, isn't it Kay?)

Then again my Norwegian sucks (I finally got my Norwegian passport yesterday!! :-D :-D. /me happy).
