Non-form based forms are straight forward, not digitally signed, not protected an have no form text field.
Portable Document Format (PDF) forms are straight forward. However, Adobe Reader does not save the data that you enter into from fields. When you've completed the form, you may be able to submit it for further processing or print it. To save the data you enter into form fields, you may complete it by using Adobe 6.0 Professional or Adobe 6.0 Standard
