The translation is now 66% complete. The only things that needs to be translated is the admin area and the text for the installation part of the script. When I wake up tomorrow I'll finish the translation and release it for download so people can start using it and look for typos if I missed some of them.
When you look through the .lang file you have to remember the charset is utf-8, so the danish letters æ, ø and å is written in html codes like this:

æ = æ  | Æ = Æ
ø = ø | Ø = Ø
å = å  | Å = Å
