Allow voting or not. Turning on Ratings allows viewers to vote with stars 1-5 of their vote for the video. And the results show in two places; A) On screen during mouse roll-over state, B) In the Analytics module which is perpetually tracked if you have Ratings turned on. The structure of the star votes counter actually reports up to 100 different levels partitioned into five stars. From a partial star to all five stars and everything in between averaged to the nearest portion of a star is possible.
