So, I've got items I'd like to put in the trading center. Problem is, I don't really know how to work the trade center so to speak.

And another thing, I'd like to create a thread where I list the items I have so I can barter with potential buyers. Where would such a thread go?

Forgive my noobiness.

When you go to the Trading Center, you just click "New Trade" and then select what items you would like in the trade and type in description what you would like for it.

For selling items you can post in the Advertising Forum. ^^

Thank you!
