A rating can always be changed by the person who received the stamps. She must click on Stamps exchanges at the left, than on Received at the upper right, than on the exchange ID of the trade that must be corrected. A new rating can be entered and confirmed. A trader that sends better stamps in a second letter deserves a better rating.
Hoi Anne-lies, dit gaat heel makkelijk, ga in de linker kolom naar stamp exchanges, dan zie je boven aan rechts received staan, die klik je aan, ga naar de persoon die je wilt wijzigen en verander de rating, dan klik je op update, en klaar, succes !
