When you are adding fields to a TimeToSignUp registration form, you have the option of determining which type of field will be entered. For email fields, select "email field" from the drop-down list so that the system knows to interpret the data entered as an email address and therefore will send the confirmation email.
To change from text fields to email addresses in existing registration forms:
- Log in as the admin
- Go to the form
- Click on "Add & Edit Fields"
- Find the email field, and select "Email address" from the Type column
