A lot of question threads have good answers, but never marked as answered. May be somebody from GHI, as a final authority, should choose the most accurate/complete answer and mark the threads. The author of the thread should still be able to adjust that.
I think that’s a good idea. No reason for us to burden GHI with this.
Perhaps an alternative would be for all members to be able to mark a response as the best answer and after some amount of time the post automatically closes and the best answer becomes the official answer that is rewarded points. This would also stop the problem with people re-opening really old posts. Obviously, something like this takes more effort on GHI’s behalf to implement and we’d rather them work on other things
It would be nice for the “Unanswered Questions” list to be meaningful, though.
