I struggled a bit when the form was completed because I failed to see where the "Print" button was located, but a rep from Customer Care (Paul) helped me and I was all set. Looking forward to exploring and using the PDF filler site frequently.

IT'S BETTER THAN DOCUSIGN
I like that you can send to other to sign just like docusign. You can also fill in the blanks. You can share the info and even print. Also is not too pricey.
What I don't like is, when I send to multiple signers anyone can sign even on my signature. I wish they'd allow set signatures per person so that folks won't get confused .

Works great, I have never had a problem.
Easy to fill in forms.
Easy to use. Everything is labeled well so you can find what you need to do quick. The files are always where I need them to be.
I haven't had any problems using this software. There isn't anything bad I can say because I haven't ran into anytjing.

When I tried to sign in from a new home…
When I tried to sign in from a new home computer, after I put in my email and password, a box flashed with information in the top right of my screen. It flashed and disappeared so quickly that I could not read it. I had to keep attempting to sign in so that each time I could read a little farther in the box which I finally was able to read and it told me that an email had been sent to my email account and I had to go there to verify that it was me signing in from this new computer. The box should not flash and disappear so fast that it cannot be read.
