After I'm paid, I leave feedback, after the other person receive the goods and inspect it and is satisfied, they leave feedback.
If they dont within about 48 hours, I'll send them a "Hey, did you get the item / Are you satisfied with it?" as a reminder. If they did receive / are satisfied, I ask...
I prefer the good ol' "Bump" in the actual listing thread. That way, all the comments and original details are there.
Sometimes, that's a good thing, sometime it's not.
