I'll be happy to be your beta tester - I just got a major non-profit site off the ground, and then, by sheer stupidity, I upgraded CB to 1.1 (for security reasons) without checking, if a Danish front-end for 1.1 existed. Now my all-Danish users aren't too happy ...
If it works, you'll definitely make my day and save me the trouble of going over the code tonight myself.
Unzip the code locally on your PC and upload the folder "danish" to /components/com_comprofiler/plugin/language (i.e., it becomes /components/com_comprofiler/plugin/language/danish
In your Admin interface, you can now see Danish in Components -> Community Builder -> Plugin Management
Hope this helps.
Thanks to ford for pointing to the file, and to Ronny Buelund for providing the translation! Much obliged!
