the way it has worked for me, is that when email is sent through the Audiogon system, I receive/and vice versa the seller, a note within my personal email account (for me, Gmail) a notice of a message and the actual message. This would eliminate the excuse, the seller didnt log into Audiogon and therefore did not get the message.
also, to address the issue with buyers not responding, the one big difference is to the seller, they still have the item and can sell it to someone else, ----in my example, I have just sent thousands of dollars to someone I have never met, across the country.
When I am a seller, I am mindfull someone has just entrusted me with their money and make sure I keep them advised and in the loop and respond to their emails timely.
