This sounds like a good idea ... maybe extend it a little. Several sections/tabs.
| Kingdom News | Markets | Events | Other |
More if you could think of them.
Kingdom News would be certain people in kingdoms could change this ... maybe it's a new rank-right that leaders can give out, or maybe attach it to one of the others that already exist. Only important kingdom news can go in there, no spam etc or the person loses the right.
Markets people could post Buying/Selling, maybe, note the MAYBE people could drop their items in there that they want to trade, and have something like main trade, only if you log off it stays there and other people can make an offer on it, you can have more than one offer. When you log back on, you see several offer for item [x] which all users have accepted. You could chose to accept one of them and take their item and they get yours (I believe this can be done with mudlib even if player is offline). Also you could say what you're looking for. If you put your item in markets, it disapears from your inventory. Otherwise, just people post Buying/Selling, like on the forums.
Events people could talk about kingdom events planned (maybe that goes in kingdom news), discuss events that happened, and request events to the EMs.
Other ... basicly like a forum, post anything, people can reply like in all of them ...

Basicly my twist on it.
I love your idea, it could be very useful.
