Forum:How to create a translation of an existing article without creating a new wiki

Hanging out on metal.wikia.com recently, and it's still very young so I figured I could contribute some Danish translations. There are currently zero articles in Danish. If I want to rewrite this article: http://metal.wikia.com/wiki/Black_metal in Danish, do I have to create da.metal.wikia.com, or is there some simpler way?
 * It is normally easier to have separate wikis for seperate language forks, but I suppose you could ask for a new namespace for the other languages. -- Random Time  20:51, July 15, 2010 (UTC)
