Okay, several times I've sold something (a site or a domain name). I end up sending the itrader feedback to the other person involved. They receive the positive feedback. However, they often don't return the favor and leave me feedback. Nothing wrong with that I suppose, but it can be a little annoying at times. What if itrader feedback doesn't apply unless both parties leave it? I think this would be beneficial and would encourage users to use it more. Moreover, I realize that this would be problematic in the case of a negative sale. So perhaps it does take effect if one person leaves negative feedback. However, if it's positive feedback it doesn't count unless both parties leave it. Just a suggestion.
