That would be in the BOI section.
if you scroll down from the main page, it is the only section in red. If you have any feedback it would be in there. Now don't go posting in there asking about how you are doing. Just keep doing good business and the posts will come. Quit worrying about your rep. Just keep taking care of business and the rep will take care of itself. People who worry about rep too much and all that stuff just scare me.
Also if you look at your posts, the trader rating part. You can click on that to see what people have left for you.
People don't always leave feedback. So don't worry about it. Look at mine. It is on six. But trust me. I have done WAAAAY more than just six transactions. Perhaps it was in one of my previous screen names or something. But who cares, that was the past. As aforementioned quit worrying and just take care of business.
Oh and get back to work.
I am officially at lunch so I can post away.
