I've just uploaded an improved and enhanced Danish language.php for Tiki version 6.2 to the file gallery.
It was recommended to me by rick99 to commit it to trunk and to the 6.2 branch but this will have to do until I get some more time.
Enhancements are mainly in wiki, forum, file gallery and calendar.
This was just what I needed for a small site. There are still lots to go.
