I hadn't registered that this had been changed, so excuse me if I'm hopelessly behind the crowd!I usually leave feedback so promptly I never see the reminders, but this was a test exercise so I've got an excuse.
Wording now is:
If you get a few seconds spare we would appreciate you leaving feedback for [seller id in here] (SELLER) in regards to the auction [auction title in here].
Click the link below and give [seller id in here] a simple positive, neutral or negative rating for their role in the transaction.
This is an automated request sent out after a specific time period since the sale date. Feel free to ignore if you don't wish to leave any feedback.
Which is polite, no pressure, and makes it clear it's the system asking not the seller. No problem with that, thanks.
