I had a trade with someone with a MUCH higher feedback rating than mine.
He received his item and paid me via paypal, but didn't leave feedback, whereas I left him feedback as soon as he paid me.
Now my positive feedback or lack thereof isn't going to effect his rating much one way or the other, whereas my rating is low enough that any positive rating is a significant boost.
Is is bad form to PM someone and request their participation in the feedback process?
If not, how long should one wait to do so?
Just curious as to how more experienced traders handle such an issue.
