I'm from Denmark too. For my part I would prefer the forum with the most likely help = the biggest, and think that english is not a real problem for most.
But a thread where issues with limited geographic interest is discussed could be interesting. People could pop a message to say hi, I live in this specific area, events could be announced and part-dealers discussed.
But for the helping out with software and hardware problems an idea from the other side of the globe is as good as one from your neighbor.
BTW: Nice to know that other folks in Denmark and Sweden are messing with the Arduino too
