Hi Kevin,
Sent you an e-mail from my gmail account.
I once left a 4 star rating on a shipping charge and the seller flamed me, too.
It was kind of easy to figure out that I did it. He had only about 50 ratings and I was the first one who left less than a
5 star rating. He put 2 and 2 together and deduced that it was me. Sent me a mean note and blocked me from future bidding.
Oh, well. I thought I was just being an honest customer.
