Just to clarify my experience....the knife was sold to a guy. No problems there. He had a PO box number and I needed a physical address or phone number, so I had to get in touch with him. HAD TO. I used the PM function to type an EXTREMELY short message. Tried starting new message. Tried editing existing messages. Tried the email function.....all no go. I get the page was reset or whatever screen, after waiting a minute or two.....every single time.
Finally I got smart and went to the Paypal page, where his email was listed, and was able to get in contact with him thru his regular email and my regular email.
This is the second time in as many sales that I have had to contact a buyer who does not list his email or contact info in their profile, and the PM and email function fail to work. Problem solved for now....as I was able to contact him via yahoo mail.
