Yes, it's true. We just added a Danish translation. Enable it here. Thanks to our tweeter and PR guy Morten!
We have supported translation for a while, but the actual work has been slow. We have now found ourselves forced to disable translations on the API documentation. It's long, technical, and difficult to translate. On the other hand it is probably of little interest to someone who doesn't already speak decent English, so I gather that this is not a huge loss.
From what I understand, the French translation is very close to being completed. We still would like someone to help us with Korean!
And for those of you who are giving up on our rating system, we are working on it. There's a reasonably promising modification in the pipeline which I hope will not be too long off.
