This is a nifty little mod I made on commission to someone. It's been about 11 months since it was commissioned, which I figure should have been long enough for them to capitalize on the uniqueness. I have a number of mods like this that I will be releasing soon.
This mod lets players exchange items after first offering the items they want to trade and then agreeing to the trade.
Commands:
/trade [name] - Send a trade offer
/acceptTrade - Accept a trade offer
/offer [slot number] - Offer an item to trade by specifying an inventory slot number.
/confirmTrade - When both parties have done this, exchanges the offered items.
/declineTrade - Declines a trade offer or ends a trade in progress.
