Go to the Swap Page:
http://garden.org/apps/swap/
Click on our swap name and then in the list of links up top, you'll see a couple new options:
» View your "bought" items
» View your "sold" items
Click on one of them to view the report.
Note: the link will only appear if you have items. So if nobody has yet claimed your items, then you won't have a "sold" link at all.
