User submissions



I have an idea for a website about movies and want to allow users to submit content, but I want to keep the content a bit more controlled than on Wiki. Besides MediaWiki, which CMS is good for allowing users to submit content?

If it helps, what I envision is, a user can submit a theme like “Movies starring Matt Damon”, which creates a list to which other users can add movies fitting the theme along with a small amount of relevant information, for example “Saving Private Ryan - Matt Damon plays the title character”.
