I don't know if anyone has suggested this previously but I had a quick flick through the topics and couldn't find anything, so....

I wanna suggest a trading centre, i've seen it on several different websites and it works pretty well, I figure it'd just make it a heck of a lot easier and cheaper for the folks that wish to trade things (so they don't have to advertise as much) I know from experience that user shops aren't generally that busy too, the trading centre would also be able to let people trade their items for other items/bones/ala$. (maybe a trading charge of like $50 could be set up too? i dunno)

the idea just popped into my head but i'd like to know what you folks think let me know if you like it or not and comments/feedback is welcome
