This might be good if ever it is implemented. And the users who are in this campaign that are eligible to join must be quality posters and not the ones who post the most. Giving up prizes for those users who posts well enough are good, because it will motivate others to post "quality" posts and not the yes-it's-constructive ones. It will also push the quality of the posts in this forum up, because basically users will strive to get that bonus reward that is already waiting for them.
