Well it's odd. I looked at the database when I had this hack installed and saw two templates called email_notify. One of them had the templatesid of -1, which was the original template, then there was one with a templatesid of 1, which was the one I'd edited with the changes.
For some reason it never wanted to send me e-mails with the updated one, though it showed up correctly if I went to templates -> edit -> email_notify. I dunno. I appreciate the tips though.
