NotifyMe functionality allows users to subscribe to an email notification service when a product is back ordered or sold out. NotifyMe records can only be created from the front end via Product Content when the item is back ordered and when the Notify Me Setting are enabled/configured.  Once the web user has enrolled into the NotifyMe service the record will be available in Sitefinity.  To view the record go to the SmarterCommerce|Other|NotifyMe. To see the email address associated to any/each subscription record simply click on the row.
