Post Ratings

An optional feature you can enable on your forums is Post Ratings.

Post ratings allow your members to thumbs up and thumbs down posts, helping to show which posts were more favoured by your community. You may only vote on a post once, and after you have voted your vote cannot be changed.

Manage Post Ratings
You can enable or disable the post ratings feature from the Admin page of your forums, under the Settings tab. Here you can also configure posts with a very low rating to be hidden by default. This can be helpful to allow your community to ignore some less useful posts (such as perhaps spam or duplicates)
