FormsCentral always submits to the FormsCentral server and right now the email notifications can't include the filled PDF form.
If you have Adobe Acrobat then you can export your form as a PDF out of FormsCentral,open the PDF in Acrobat, add your own submit button which would submit the filled PDF to your email address and distribute that PDF to your fillers. In this scenario FormsCentral wouldn't collect or manage your data.
There are a couple of options for you.
