Dear Limesurvey team

I would like to edit the notification e-mail which I am sending to the participants once they have completed the survey. I am sending them the e-mail via the {INSERTANS:34X344X3} workaround. Now I am trying to edit this mail by editing the admin_functions.php but the changes I do, do not apply to the notification mail. Can somebody maybe point me in the right direction. Do I have to edit another .php file?

Thank you so much in advance

Yves
