If you send a Risk Questionnaire from within the HiddenLevers system, then an email signature will automatically populate with your name and email address.
If you'd like to edit the signature, click on "Survey" from the Dashboard and then "Email Survey." You can edit the text of the email as you please, including the signature. You can add text as well as pictures.
Once you are finished making edits click "Save as Default" to have your changes become the new default text when you send a survey from within HiddenLevers.
