I'm wondering how to change the text of the autonotification that goes to the admin. For example, if I use a volunteer form (so I can use the check box feature) for a contact form, I can change the email to the person who filled out the form, but can't figure out how to change the notification email that goes to the admin receiving the notification.
I would much rather fix the underlying issue here, which is that you need to use the volunteer signup form to do something that has nothing to do with volunteers than make this notification email changeable.
So the feature here is an additional to the signup form that lets the person tag themselves with checkboxes.
FYI, if you only want them to be able to specify one classification/tag, you can already do this with the Signup page type. Multiple ones would be a new feature.
