Each contest has specific rules for defining a winner. They are shown in the contest page. The voting can be public or by jury of experts or it can have both of the types of voting.
You express your public vote for a media by clicking on it and choosing its assessment from 1 to 10.
Once given your public vote for a media, you can only vote for it again by the WINGS voting - voting with WINGS payment.
