Hi Steve,
You have a very good question here. Have you sent a support ticket to get this info from Auctiva?
Before I opened my basic store and got Selling Manager with it, I used to subscribe to Selling Manager Pro and with it there were a lot of auto emails that went out based on the situation. Also, the auto feedback worked really well, even though I too, have not had one of those kooks, I talked with others who had good results with eBay's auto feedback through SMP.
I would sure be interested in the reply you get here or from Auctiva.
