It worked like a charm, but although I figured it would be a paid service, but it would have been nice to know it was and how much before I got started.

At first, I didn't understand what I needed to do first. I filled out the form I pulled up and then submitted it, but was sent to a page to choose which plan I wanted. When I realized I needed to choose a plan, I chose one, but then I had to fill out the form all over again! Then I submitted it, but the form again, but it wouldn't appear on my list of filled forms. My list only lhad a previous form from 7/15/2015. I chatted with a representative and she helped me get my second version on my list. This rep was extremely patient and nice, and did all she could to help me. I'm very happy I spoke with her.

I like everything except when filing in… I like everything except when filing in the forms the lines do not automatically wrap to the next line. I have to know to stop and manually go to the next line, Maybe that could be fixed. Also, when I tried to share the completed to form via email; nothing was received by the recipient. Only via fax did information get received.
