Please do not 'Spam' the in-game chat system pleading for items to buy or sell.
If there is something in-game you need you can: 1) Check the Player Vendors by using the [sv command. (Type [sv followed by at least 3 letters of the item you are searching for) 2) Talk to others in-game (using Private Messaging not Public Chat). 3) Post your request with item information here.
If there is something in-game you want to sell you can: 1) Place it on your vendor. 2) Place it on the in-game Auction System at the Public Market in Arete. 3) Post the item information here hoping for a Private Message from a potential buyer.
NOTE: Selling/Buying any UOT item to/from another player for real world money is not permitted and is bannable.
