Kinda covering the idea of "How important is the "role" in role playing" a bit, but it would be great if you could "pin" notices to the board directed at individuals, and then when checking it, a "personal messages" option could be displayed.
Although this can be done via forums etc. I think it would be great to have it as an in-game function. There is clearly a serious attempt to create a genuine in game economy, which I have seen the beginnings of personally, though the ability to place orders with people offline that they can pick up on would be awesome. The facility could be used to advertise guilds, open requests for people to form groups for specific purposes and many other reasons, however an in game cost should probably be attached to some options.
I guess I feel keeping as much of the experience in game enriches it.
