OK, I have a downloady store, so it is in my interest to have an email sent out when customers' echecks clear, so they know to come back and download before expiry.

I have managed to install the "zen_mail" function in the right place, but have set the address to my own email until I get the email looking proper.

My question is whether there is a language file or whether I can create a language file for that module? I don't see any language constants in the entire paypal_functions.php file (which is where I have the zen_email). Thanks :)
