Add your own listing by clicking the "Add New Item" button at the top of the page.  This will bring up a simple form where you can enter information about your item and even an optional photo.  After submitting the form, you will receive an e-mail with a key number you use to confirm your listing.  Once confirmed, your item will be immediately added to the exchange.  It's that simple and there's no waiting.

Later, if you'd like to make a change or delete the item after it's sold, you will be able to.  Just click the Edit - or Delete - buttons that will appear next to your item.  Note that these buttons will only appear next to items you've submitted and only when using your computer.  No one else (except the web master) can edit or delete your submissions.  Also note however, that submissions deemed to be inappropriate for this web site will be immediately removed.
