The BYC Staff has made some policy changes to the BSA system. These changes are noted here https://www.backyardchickens.com/forum/viewtopic.php?id=250783 Namely, we will no longer allow sellers to request that buyers contact them via PM to complete the auction. All auctions must be purchaseable either via the "Buy it Now" or bidding options only. Buyers and sellers are not able to leave feedback unless purchases are made using the auctions system. Also, we have linked to the explanation of the Proxy Bidding feature. There has been some confusion about how the bidding works. Thank you!
