I hope that they can implement a Trading Station soon :)
For example:
I want to trade in my Zille, Tii, Cosma, Humbaba, Alph, and 2000 currants for 5 Friendly Emblems. So, I will post all my tradeable items in the Trading Station and will automatically trade with the first person who can satisfy my need for 5 Friendly Emblems.
The trading station won't be in-game like the shrines and stuff, it will be more like the Auctions pages.
I think some people will find this really helpful. ^_^
