Some users want to change the content of the automatic email that is sent from your store when a customer creates a new account.

You can FTP into the file, edit the content and save it back.  As ALWAYS...save a copy of your file before you replace it so you can quickly fix any issues.  When you are done try creating a new account to test your work.

To make this change, the file is in the "/public_html/includes/languages/english/create_account.php"

You can change the text of osCommerce CRE Loaded Welcome mail here.
