I need someone to show me how to use it.. the three times I have used it, I felt like i was fumbling around in the dark trying to figure out how to do what I wanted to do

Quite simple and handy to fill. I would have preferred using my own signature on the completed form but I had difficulty loading an image of my signature.

It's great
It's great. Not as good as adobe in the areas of text replacement or image addition. It is also not as sophisticated for selection mechanisms. If you need to fill in documents or create PDFs this is a solid application that can do the stuff that you will need quickly and cheaply.
