Aye. The Trade Count feature is something that was just added. I tried to remember everyone I've traded with so I could give them proper feedback, but that was way too hard. I know I've got several trades coming up as well, I've got three packages sitting on my desk ready to go, right this moment.
The feature is very easy to use. From the Knight's profile for whom you wish to leave feedback, click the appropriate link. Then just fill in the blanks.
