I don't know if it is an option, but would it be possible for members to be able to edit feedback that they had left. The idea would be to give instant feedback on new traders. For example a whole heap of people have been messed about by 'Drop' over the last few weeks. If all of us had posted neutral feedback as soon as we had suspicions.i.e.: 'Domains sold, payment pending'. Then it would have been very clear what was going on, without jeopardising the deal. When paid, it could be changed to positive.
