(Let me know if this has been mentioned before.)

I commonly exchange my items for pets in lieu of silver. I am sure other players do it as well. While I have had no problems rise from trusting the other party of the deal, an exchange system would make both sides feel safer about the trade.

Private exchange for when deals are made and/or public, and people making a deal can simply watch the exhanges. They make the offer by asking for an item for the pet they have, and the other person accepts if they have that item.

Perhaps the coding for item exchanges could be re-used and tweaked, and hopefully a whole new system doesnt have to be coded from scratch.

I agree with you.

I think this is a similar topic.

I agree with everyone!
