I know that in the past classic has rejected the idea of a trade system but what about a auctioning system :?
The idea would be to allow players to sell their unwanted mounts, hats, furniture, etc. to other players :3
Players could view a item for auction and make a bid. If the seller likes the price then the item is sold.
An to prevent scamming their would be a 1 hour return policy for buyers to return the object and get a full refund. There wouldn't be a return policy for sellers because if your selling an item you can't buy ever again I seriously doubt you'd miss it.
Plus an incentive to the owners of classic, would likely see a increase in the purchase of gralats. Because this would allow newbie's with money to buy cool stuff and people like me to save up to splurge on a cool hat or mount :3
