Rating in forums

[kmk]

When I should enable the Rating for forum? How it works and how it affect our forum management?

It's not really a question of when. Rather, do you need your users to be able to rate topics (from either 1 to 5 or 1 to 10 stars) on the forum?

For example I've seen some sites using the rating function for a forum where topics are actually reviews of products and people vote the topic based on the review's quality. Do you have something similar that requires enabling the rating option?

As for how it works: people can simply vote X stars but the voting itself doesn't really impact forum management. The only change is that you'd be able to order topics by total rating (or maybe filter by X stars; I can't recall right now).

No, it doesn't give any points.
