We have a reputation system that we use on our other forums. If a bunch of people say they would want to use it, we can turn it on. Reputations go both positive and negative. A lot of people don't like having them turned on.
If we turn it on, we let reps go as they go -- meaning we won't be removing a bunch if people complain.... .🙂
You can also do star ratings on threads. That should be 'on' already.
Brad!
