Alcira S
It was very easy to Fill out the PDF. Then I was suprised I could also mail it, from the same website. I can upload a PDF and have it mailed, even by Certified Mail. That you can mail or fax the PDF. You can like email to fax. Which is very good. Especially since I don't have a phone anymore, let alone a fax, since I just use my Cell Phone. Technical support is terrific. They are always availble, they know everything, they are very helpful. For example, one technician let me email him my PDF, he fixed it for me, and emailed back to me.
