Yesterday I implemented the Rate module in Drupal 7 on this website. It is now possible to give a thumbs up or down for my blog, drawings and photo galleries. I have my doubts if people actually will use it, but hey, because we can we implement it
This module will give a percentage of how many people liked or disliked something, when no one has voted yet it will default be 50% like and 50% dislike. If one person likes something it will be 100%/0%, two likes and one dislike will result in 66%/33%, etc... For the photo galleries the voting will be for the whole gallery and not the individual pictures, for drawings and sketches you will vote for the individual drawing or sketch.
