Some players are already starting to create fake parties, and only using the party name for trade-propositions. If this prevail, we're going to get disorganized LFG-List, half filled with trade-fake-parties (like in Diablo 2).
That made me think, maybe the developers could implement an extra social-tab for trade-posts, so that those "parties" does not mess with the Public-Party list.

This Trade-Post tab can be used as a third way to trade items beside trade-channel and trade-forum:

If you open the tab, the proposing player would be shown, so you can message him. (optional including some text and items)

What's the difference to an auctionhouse, many player don't want:
- Trading is still personal, not automated. The social aspect is not lost.
- Offers are not sorted by price. You also cannot see all trade-posts at the same time. The barter aspect of different offers remains.
What's the advantage of having that extra tab for trade-posts:
- Player don't need to create fake-parties for trade-propositions. The "public-party" list stays cleaner.
- A second way to find ingame trades besides spamming the trade-channel.
- Players can leave a trade-post and then continue to play normally.

Photoshopped some images to visualize. Opinions are welcome.
Edit:
Additional infos, how i would imagine it. The extra-tab would only show a few trading-posts, similar to the list for public parties. You need to be online and can have only one trade-post. More convenient than now, but not too easy.
