In situations like TECSHARE's, you can (if you trust TECSHARE and disagree with Vod) post an additional positive rating responding to whatever Vod said. This will counteract Vod's negative rating.
The meaning of having "green" trust is now diminished and will be similar to what was previously the meaning of having black positive trust.
Oh, good point. I changed it so that you have dark green trust if your score is 5 and dark green if your score is 15.
