When requesting or posting that you can temp trade, start your topic then look over to the left and use the drop down arrow where it says "View More Emoticons" and select Resources so you can use images.
*When temp trading you need to have one trade partner in your trade circle that you know is active (checks nation regularly/daily) so that if you cancel and need the trade back the same day, they will be online to re-accept your trade offer.
*Also if you can temp trade, be sure to notify your trade partner in advance so they know you will be canceling and resending the trade often.
