eBay User Feedback Hack

[groovesalad]

I trade a lot of live shows of artists such as Dave Matthews Band, Phish, Grateful Dead, Howie Day, etc, etc. I was wondering if there was a way to create a hack on a persons profile that does the exact same thing as Ebays User Feedback. You'd be able to check if the trade went Positive, Neutral, or Negative and be able to write a small response about the trade. I'd like to show the numbers of Positive Feedback on the Users Profile (obviously since this will emulate Ebays User Feedback), but as well as the Welcome Message on the main page and on their Postbit. Is this possible?

Here is my webpage that I'd like to implement this on.
