I'm not sure if there are differences between different Mailman versions but I'm using Mailman version 2.1.14-1 and on it the /members/add form defines `'send_notifications_to_list_owner'` instead of `'notification_to_list_owner'` so this might be wrong or maybe there should be some checks for using different variable names for different Mailman versions?
