There's already been a discussion about DA forums in other languages, and there is at least one, in Dutch.
The problem is that when you post on the main DA forum you can get answers from the largest group; most of us, in fact even many of us who do speak other languages, just don't have time to monitor multiple forums.
There are DA skins available in several languages; if you're interested in doing translations into other languages please post details of what you're offering to do.
Note that some of DA is hardcoded directly into the compiled C++ source and cannot be changed even with skins.
