If you are having the form-submitted data stored in an Access database via the
Database Wizard, then you can create a confirmation page that they are directed
to automatilcally after they submit the form.
On that page you can say whatever you want, plus you can Insert Confirmation
Fields. So that when Joe Dokes signs up you could have the confirmation page
Joe sees say "Welcome Joe Dokes, happy to have you with us or whatever)
