Would very much like this, mostly because it'll help track down harder to obtain mats. Let's say this: There's "Person A" who has 5k dragon bones they wanna sell. Then there's "Person B" who wants to buy them. They live in very different time zones so they can't be online around the same time. Being able to post items such as that in a trading post / player shop / ge would be able to solve issues like this. However, I am a new player (Within 3-4 days new), so I don't really know much about how this server operates 100% yet.
