I had a domain name at Bodis but sold it some years back. The new owner has left it there with my contact details. A potential buyer for the name wants to buy it and gives a figure. I get the message. The new owner can be found via whois. I don't know if the buyer has tried that already. I could - Tell the buyer I am not the owner and leave it at that, Do the above and point them to my sales page that has similar domains at a lower price, Contact the new owner and tell them they have a potential buyer, Try to act as a broker for either the buyer or seller, Offer a lower price to the seller, buy it for myself and then sell for a higher price to the buyer. So what would you do?
