Since istorya.net does not have an eBay type of selling-buying format. I would like to suggest on the Buy and Sell section to have one STICKY Thread (in each category) that contains updates of Good Seller and Good Buyer istoryans. This will improve, though not to the full extent but at least, protect the seller or the buyer's reputation or even his/her own safety.
I don't know if it's possible for the Moderator to update a pool or rank of each member's reputation on the first page of the said thread, but within the thread itself the parties involved can go through the posts to check each member's background before the transaction pursues.
Good Seller - Good Buyer Thread. Dapat naka sticky! Please support.
Thank You
