on the html-based form http://www.samtaleterapi.com/oversigter/psykoterapi.html there isnt the functionality i want
it can only be filled out and printed
what i want is a form that can be filled out, saved locally on people's own computers, and and that the local copy can be edited and saved anew continually
can PDF do this?
can the end users edit and save the form with no other program than adobe reader?
if so, is this a specific format of PDF?
and if so, how do i create it?
You can indeed create a PDF form that can be opened, filled out and saved by users of Adobe Reader. It simply requires one of the later versions of Adobe Acrobat. It has a function to enable this ability in PDF's.
The one down side is that there are usage limits (how many times form data can be collected) that you would want to familiarize yourself with in advance to be sure you don't violate the EULA. Exactly how thos limitations work are up to interpretation...
