When trying to save a completed document to my hard drive it becomes confusing. I cannot find the saved files anywhere. Other than that the program is great.

Easy to use, unlike other fill and sign apps, it can tell the right size text. It can tell the what parts of the document requires the text. The variety of templates to use for common forms needed for most people. Also a generous 30 day trial A ++++

There was a big learning curve for me, but think I have a fair handle on it now
There was a big learning curve for me, but I think I'm getting the hang of it now, once I've finally finished a Fax Form cover sheet.

Sometimes a bit complicated but no other company has my attention yet
This software can edit, find, fax, email, and fix documents. fax is strong, and blacking out and deleting items is nice.
Sometimes you can see where old edits have been made and they print bad.

By far the most functional PDF editor i have used... Not that i have used that many, but this one was a breath of fresh air considering the other broken standalone PDF editing apps

I really enjoy using PDF filler. I consider my self to not be computer savy at all. I would really like it if there were a webinar to help people like me understand this app.
