Trade
Trading is used to aquire commodities and items from cities, NPCs, and other avatars.
Trading uses an auction and bidding system in the Comm (F2). The buyer commonly starts by asking if the seller has anything or something specific for sale. The seller then list what is for sale, either as an auction where the buyer has to make a bid, or posted with a predefined price. No matter how the seller posts the commodities for sale the buyer can make any offer they believe to be fair, and then the seller has to accept the bid they want.
