As someone who loves to trade and is a risk-taker, I think a trade tracker could be convenient in more than one way. I've traded hundreds of times this past winter and spring and have had very few disappointments. Having a trade tracker that we can make public listing trades with members would be nice. This way, others can see who has traded with whom and do their own checking if they'd like to decrease risk. We wouldn't have to make feedback public--or even what was traded public, if we don't want to.
I do appreciate the opportunity to make it up to others one on one, and don't like the risk of being blasted publicly because someone's having a bad day or a package was left out in the blistering sun for days, or for an honest oversight on my part. Honestly, I think most traders with feedback on other sites don't get negative feedback because most other traders would rather remain silent about their disappointment than stir things up. I'm that way myself.
