"Voting" on the simExchange is now known as "bidding" on content. The reason for this change is to reflect the evolving concept, which requires users to put down DKP to take an opinion on user submitted content with the potential of gaining or losing DKP. Appropriate for a prediction market, right?
As you know, you now gain 10 DKP for each player who bids the same way you do (after you) on an article, image, video, comment, or user submitted game. However, it costs 25 DKP to bid on content. Submitters of content also gain 200 DKP for each up bid and lose 100 DKP for each down bid. Commenters also gain 100 DKP for each up bid and lose 50 DKP for each down bid.
A new Bids on Content tutorial is now available in the Help section. The Rules and Glossary pages have also been updated.
