It was just what i was looking for...im not very computer literate but WAS NOT hard to learn. I do think a few features could be added or made easier. I WAS NOT HAPPY WITH THE COST. Its mighty ridiculous! For the amount of money i spent and the length of time... S***, unless you are in the business of "screw ups" "uh-oh"ers, the presidents Secretary for his twitter account...or a lawyer. I don't think you get enough time for the cost. And VERY UNSATISFIED with the small print that is located UNDER the nice AFFORDABLE FAKE SALE PRICE at the beginning of the website

Great software Excellent, the software is very easy to set up and use and gives me all the functions that I need to edit documents. Ease of use. It allows us to edit documents easily and send them out to clients for signature. Lack of choice of fonts. When you edit a document, the font is automatically changed, meaning you have to change the font throughout the document.
