I'm creating a site where most of the content will be user-generated from blogs and forums. It will act as a political news/opinion site. Right now I'm going with Wordpress but I'm interested in WordpressMS. With WordpressMS users will be able to create their own blog instead of just authoring the primary blog. However, I'd like blog content to be selectively integrated into the index page. With WordpressMU, is such a set-up possible or will it be hindered by the separate blogs? I guess I'm asking: which is better for a multi-user site: Wordpress or WordpressMU? Ideally users would be able to post their own content but only approved content would be promoted. What would be the best way to manage this?
