"To vote select a star rating for the stars labeled vote. 5 stars mean strong yes. 1 star means strong no. 3 stars means weak yes."
You can change your vote on a topic at any time by returning to the bug report / feature request page.

Although voting 1 star will drag down the average, since it adds to the point total it doesn't really have the effect of a "strong no." Maybe there should be a negative vote?
