Could you add an option (that can be disabled or enabled at will) for whenever someone posts a comment in a movie you submitted?
ex: I have a movie "60 mage pvp guy" - someone posts a comment in it long after its been out when i'd never check it. At the front page of the website, maybe next to the avatar, it could say "New Comments!" and clicking the link would show a page of the new comments you received in whatever videos.
Would be a nice feature for the times we do get comments on old movies we rarely check on.
