you should give more guidance. It kind of feels like maybe you're not serious about selling. You're system of having a huge list is difficult. Hard to track what has been offered on which domain. Might be easier if you broke them into smaller groups each with their own thread.
At the start of the thread the list is updated once I get an offer with the highest offer I am serious about sellling and have already accepted offers on 4 domains If I determine the offer is substancial I will agree and let the user know if I accept an offer.
