I dunno i don't really see much need for it. Someone suggested this at dd a long while back and it no one seemed to get behind the idea, and infact it received a lot of criticism.

I mean what are we rating the quality of the file or whether we like it?
There's clear difference between opinions on everything. Some people think really bad rips are 'good quality' when they are really technically bad and look very poor. Some people also have really contrasting opinions of movies too. I really contrast with max, he likes some really loathesome movies like eurotrip whereas i think they are diabolically shit, so flat voting is rarely very useful. For a useful vote there needs to be some more advanced algorithm for recording who voted for what and then linking to other highly rated movie to build up a knowledge database. Without it, i don't see how its any better than say like IMDB, which has a score for movies already (and the links should already be included).
I think the polling option should already be turned off in the release sections, if not, its a permissions mistake i made when setting up the forums.
I do however like the notion of a rating and recommendation system. It was always my intention of adding this functionality to the frontpage at some point in the future, but for the forums I'm not sure it would work.
