hi Mamamoo.....
ok, if you click on my user name you will come to my info page. Near the bottom you will see "About Me" "Contact Info" "statistics" and "Feedback Score" as well as a few other tabs. Click on the Feedback Score and you will see a link that says "Leave feedback for CelticGirl.........this is where you can leave feedback and I am pretty sure this is what updates the trade rate. I will leave your feedback as soon as I receive the coupons. Have a nice weekend!
