This forum, or so i thought, was for brainstorming. I am not saying what HAS to happen or i'm leaving or anything like that. I just know that this would be a way to encourage people to do as you wish.
In order for there to be a authentic RP environment, there has to real dialog, but also real occupations. Your character can't simply sit around all day and do nothing but RP. Your character needs to bring something to the world. This could be nothing but providing raw materials for crafters, it could be crafting items for sale, it could be ridding the land of creatures that threaten the citizens of the city you are from. I think that introducing occupations could help in this regard. I have been thinking about it and if you meet X requirements, you should be able to apply for a paid position in-game. For instance, if you get a 10 weapon skill, you can apply for a position as a sentry or a rat exterminator or something.
There also should be a NPC character that can act as a merchant for when the character that has X resource is not online for someone who needs to craft Y. Everyone agrees that it is difficult for everyone to be on at the same time or for extended periods of time, but until we get something like this, there will not be a realistic economy and everyone will have to be a generic character. By example, I cannot ONLY be a weapon crafter, because i will have to continually go out mining to have enough raw materials to work with.
EDIT: The Auction tab is a good start to a merchant. The seller should be able to put a item for sale in the possession of the merchant with a price tag. IF a player purchases that item, then the money can be retrieved by the seller when they are next online.
