It was confusing at first but once I worked out my own bugs it worked very well. Filling out multi formatted forms are cumbersome in changing the markings needed.

I have needed something like this to fill out legal forms instead of using a typewriter. I searched online and found this, then our attorney said this is what their office uses so we bought it. It is exactly what I needed. So thankful for it.

My original reason for joining was just to try the program and use the conversion from PDF to Word feature. Our club has need for developing forms and sign in documentation which I am exploring your features. Not as easy as I would have liked. Good product so far for my needs, but I'll make a final decision towards the end of my trial version.

I needed to print but had to wait to get ink for printer. Two days later I couldn't find the document to print and one of the Reps from your company helped me find the documents and I was able to print them. Thank you.
