I am using WordPress as a content management system for my website, as well as my blog. Revisionary looks awesome and seems to fill a major gap in the WordPress system.
A feature I would like to see in future revisions is the ability to customize a revisors' privileges. Since I am using WordPress as a CMS, I want to closely monitor and approve changes to the pages to make sure the changes are consistent with the company image/voice. I don't care as much about blog posts because they are attributed to a user and don't necessarily speak as the company's voice. So basically I want my users to be able to contribute changes to pages with my approval, but be able to post to the blog without review so they can have an unfiltered dialog with the customers (and my time isn't wasted constantly approving posts).
Again, great job filling a need in WordPress. Hope that my feature request is possible.
Thanks,
