Thank you BlackMuddler,
As you have noticed, your translation is already published. I have replaced flag icon for better one (i think). I hope you like it.
Ok I've found a mistake, and I will fix it ASAP. It was BOM header in danish.php... sorry, I didn't check the BOM headers, and on my template I didn't get any errors, but it was due my server settings. In five minutes it will be fixed.
Danish language FIXED!
