longroad, thanks for the suggestion. We are always interested in receiving suggestions from members.
What we have at the present time is some sticky posts in most of the forums that feature some of the best threads in that particular forum.
We also have a Hall of Fame thread
Hall of Fame - Best Words of Wisdom from 5 Star Members That thread honors some of the great posts rather than outstanding threads.
Your suggestion does bring to mind something I've had in the back of my mind for a long time. It isn't exactly the same as you suggested but it is aimed at achieving the same thing in a different way.
We will discuss this as well as give some thought to the idea you have suggested.
