This module adds a page to the Ubercart reports page, allowing users to list the customers that have purchased a certain product. It also displays a text box with the list of customers' email addresses. This allows the admin to easily contact users that have purchased a particular product. This can be useful for products such as event registrations, where event info may need to be manually sent to all the registrees.
UPDATE March 30, 2009: Fixed typo causing first name to not appear properly.
