I don't know if any one suggested that, but yeah.
So simply like an Auction place where people can put up their neopets stuff for auction on clraik for USD.
Or something like that. Ah and clraik should charge a little fee like 5%-10% or something for what the item sells for.
Isn't that basically the same thing as HB ?
And if you mean something similar to the Auctions on Neopets, that'd only work if people had their paypal somehow attached, so they can't back out when they win an auction. If not, it'd turn into troll paradise. Though I doubt people would want to do that.
I'd say no.
