go to the market and look in the far right colum labeled "in stores" that is the list of the resources that you own... click on any of the resources that you own and then post them on the market by Price in the far right column... notice the Minimum and maximum prices and type in something between those two numbers... then below that type in the amount you want to sell, anything the is the exact amount you have or lower will do and then click on sell below that... it will take a while, 10-45minutes or so, to post onto the market and then someone should buy it shortly after that and you will notices it on your "important events" screen once it has been purchased. gluck.
