Something which many people have wanted for a long time, has been posted in an article on Puhekupla - Trade Settings. Users will be able to go to the room settings and choose whether trading is allowed or not, no matter what category the room is in :D.

Edit: as in the image, there's also the option to allow only the room owner to trade; which will be great for Habbox Events and various other rooms :).
