I created a PDF form a couple months ago and it has a Submit via email button. It submits the completed form in PDF format. It worked great with no issues. The people who filled out the form were able to submit it with no issues. They all have Reader and not Acrobat professional.
I go and create a new form today, and it will not email the form back in PDF format. It will in XML. Is there a reason besides "Reader does not do this" because my other form works perfect on machines with reader.
