I've been trying to encourage users of my site to submit more reviews for the films that are posted there. However instead of reviewing they just write a comment. See here: http://www.studentfilms.com/films/little-red-riding-hood-short-film-youtube.23/#comment-20 The interface is a little confusing and people think they are reviewing and rating the film but they are just commenting. Is there a way to make it so that in order to comment on a film (or media item) that you first need to give it a star rating or it must be your own film? If there is not a way - is the design of the backend of XenForo Media Gallery done in a way that an addon that would allow this be simple enough to create?
