Magento

Hi—I’d like to add a Bcc address to the Send Product to a Friend so that I can see what people are emailing each other and saying about our products.  I use this on my custom OS Commerce store and it works really well.  (I suppose a better solution would be a ‘Send to a Friend’ report in the admin that displays the most popular sent products along with user comments on them, but I think this is a big feature whereas simply adding a Bcc would be quick and easy).

Any ideas where in the code I should add a Bcc?
