Auction house

Yo i figured i'd ask, why are you guys posting individual buy/sell threads, and not creating an auction house with what everyone is looking to buy/sell, its a pain in the butt to look at every member's inventory if looking for something specific, why not simply create a virtual game for the purpose of an auction that updates itself with sell/buy orders like you see in mmos ?
Just because it would be a very complex system to begin with, and we prefer to leave the legitimacy of each seller to themselves to prove. You can also very easily search through all topics in the Selling & Trading sub-forum by using the Search function inside that forum.
