I have been looking to modify the email order receipt template. I believe I found the template under skins/mail/en/order_advanced_changed/body.tpl.
<p>
{t(#Your order has been changed#,_ARRAY_(#id#^order.getOrderNumber())):h}. {t(#Thank you for your order FOOTER#):h}
<hr />
<p>
I would like to modify "#Your order has been changed#,_ARRAY_(#id#^order.getOrderNumber())):h}" to say "We received your order on "DATE TIME".
Is it possible to do that?
