Overstock buyers are a bit different in that many of the buyers come over from the Shopping site. So you deal with lots of newbies. If you let your eBay buyers know you are listing on OVerstock as well, they often will register and bid on Overstock. Especially if you move items to Overstock for which you only have 1 of, and they want it. They will bid at eBay and Overstock. Then because you use AW2000, you can group their winning bids onto a single invoice and save them money. My buyers love it.
Before you start listing on Overstock again, join the Subscription pricing plan. You can manage your bottom line more easily. In essence, you pay a flat fee for listing x amount of auction over the course of a month. I have included the URL link to the page on Overstock about the Subscription plan.
The email address is firstname.lastname@example.org
Tell Joe and Byron I sent you over. They will take good care of you.
The emails you are receiving concerning "Be my friend" is a personal network thing Overstock has set up. I am not much on the friends network thing. But others seem to feel more comfortable doing business with someone who belongs to a network of someone they know.
Something else you might try inserting into your listing template as a page component is the feedback site. It is allowable on Overstock to display the feedbacksite.com. And it shows how many feedback you have on eBay. Makes buyers feel better knowing you have been in business for a while.
