More than a year ago Merit System was integrated to Bitcointalk forum to make forum messages more informative and quality (or should make it)
That is the question\idea: Why Bounty campaign starters/managers don't use that?
For example it would be an additional bonus for Signature Bounty participants if their message will be merited. It will confirm (in ideal) that the message will be detaily read and estimated and signature will be noticed for sure.
