How use the submitted form information in submission confirmation message?

[Sashkow]

You provide ability to set alternative form submission redirect link via admin interface and a signal which allows to manipulate the newly submitted information. Can I somehow use newly submitted information to construct the submission response message for user? To copy the user's responses back to user when they just performed the successful submission, for instance. At the moment I am just copying generated form html code, pasting it back to template and altering html form's action attribute.
