One of the innovative new features on vBulletin 4.0 Publishing Suite is the cross-publishing "Promote to Article" functionality.

In the spirit of promoting content discovery, we wanted to create features that will allow content to flow between Forums, Blogs, and Articles. For example, there might be a really popular post in the forums, but unfortunately it is buried inside page 13 of a thread. We will now have an option (if you have permissions) to “promote” a forum (or blog) post as a new article on the homepage.
