Once you have opened your form you can then simply copy and distribute the page URL listed on the open/close tab. Additionally if you have a PDF workflow, with an imported PDF, you can simply distribute the PDF.
I had distributed the PDF, but when filling out the form and pressing SUBMIT, nothing happens. The data is not transmitted; the user doesn't get a completion message. So I figured I had distributed it incorrectly. I had gone outside of FormsCentral and attached the form to an email. Was this correct?
Users must fill out and submit their PDF using an Adobe Acrobat product. This means either Acrobat or the free Reader. Filling out in other PDF viewers or in browsers tend to have unpredictable results.
