Let me say this:
Feedback is given to a member done here on the boards and not for the sake of leaving feedback due to doing deals elsewhere. Heck if I could do that, my feedback would be much higher even with the prior deals done already when there was no feedback system.
Feedback is not earned any other way. If you have done a deal on feedback link it to the thread. I have done deals through PM's but because of a thread made on the boards.
Its very unreliable to say an actual deal was done here. I have done deals outside the forum boards and members will mention that but feedback will not be made via the trader system. I can speak of quite a few members I have done deals with on different forums but that does not warrant a feedback point to be awarded here.
