I haven't seen anything that would suggest we can't respond to feedback, negative or otherwise, the same as always. And I agree, a well-worded response is going to become even more important now that eBay is forcing us to be dishonest about buyers. If we can't leave a negative, we have no recourse other than not to leave feedback at all, and to my way of thinking, that's a lie of omission.
On the west coast we've been golfing pretty much all winter - and I can't hit the 9th green from the 8th fairway either, but I almost aced number 4 from the 8th tee!!
