I completed the first PDF form and it was a little tough maneuvering through the documents, savings. It was a little disingenuous to wait until I was finished to document to find out that I would be billed annually as apposed to monthly, when the advertising gave the amount payable monthly.

It took a while to begin to understand how this works. I would definitely like to attend a webinar to learn more about it. After I fill in all these forms I send you, how do I save them to my computer? Thanks, Joyce Wicks

I think your site is well designed and has substantial potential. But being unfamiliar with all the choices, my initial effort at using your site took a little longer that I had hoped it would. But that is a minor critique. i'll do more exploring at a later date.

the biggest difficulty I have is when I am trying to re-order documents (move them left or right) -- it is just very difficult to see them. I wish the functionality allowed for enlarging the docs so that I could see what it is.

What is a Digital Certificate and How can I View it?

The usage of a digital certificate is a kind of authentication to keep track of all changes made in PDF files. It comes into action after the complete document is signed by the last authorized certifier.
