I do not think there is a forum system that can take votes, then average them, so we would have to do all the math ourselves, which could be time consuming because everybody could give their ratings.
Perhaps the people who give the ratings are those who always are able to watch our matches and are just a select few of ten or so individuals. I could also see some people sabotaging the ratings by giving Del Piero a bad score just because he likes Zlatan, but that's another story..
