Add Radio Button to Document for E-signature via Python API

I have found forms through PDFfiller that I could not locate anywhere else--wonderful tool! It's fairly intuitive, but there are some cumbersome issues related to printing--too many steps--could be simplified.

What do you like best?
In our busy world, it is great to find a tool like PDFfiller to make things easier and to make sure private information is kept private. We no longer send attachments that can be read in an email that has sensitive information. Using templates has cut down our document sharing time! We now create a template that can be used over and over again. The big win in the form filling tool is the ability to add validation for the data entry.
What do you dislike?
The only complaint I get from users is PDFfiller documents are not showing up in their primary inbox. They have to search for them. We made it mandatory to check the box to send a copy of the email notification to our email address. This has made it easier to forward the email with the secure link to the recipient if they can't seem to find the PDFfiller email generated to them.
Recommendations to others considering the product:
Really take a look at your existing document and take the time to setup templates.
