We now have a user ratings tool — as of now it is only on Forum posts. For every post in any forum, you can give it either a thumbs up or a thumbs down. Every member can vote once for any given post. See the Post Ratings and User Karma section of the FAQ page for a full explanation of the User Ratings system.
Topic ratings are shown in group and forum listings view using the rating of the initial post.
Only logged-in users can rate posts.
Hopefully this system will help the Wordlab community to praise and police itself.
Below are example posts with different ratings applied.
