Forum:Copying Wikipedia articles to Wikias

I've been trying to find the rules on this, but I haven't had any luck. So what's the rules on copying an article from Wikipedia to a Wikia? For instance say you wanted to copy the Wikipedia article for Lex Luthor onto the Superman Wikia. How would one go about doing this, or is it completely disallowed?
