Ask HN: Software for running a school newspaper?

I've found myself the web editor of the school paper at my college. It's being resurrected from a long slumber, and I'm building both a web edition of the publication and something that can be used as a backend for submitting articles and having them pass from writers to copy editors to general editors to the layout people.

Money for software isn't a concern, but I have a preference for OSS. Right now, we're leaning toward a Wordpress-based front and and a private MediaWiki to manage articles and so on. Something more elaborate (hey, what's Django for, right?) and customized is not out of the question too. What do you think about this? What would you use if it were your project?
