Is it possible to have "internal" fields on a form that do not show up for the registrant? I.e. A form that would be used for a course registration could have an internal field for "date registration complete" "date course complete" "course score" etc.
You can add columns to the response table to store additional information that you don't want to show up on the form. Since we don't support multiple edits of a form it is not possible to have multipart forms at this time.
