I really like the program however I do no like the fact that you have to pay extra to verify a signature. I believe this should be included in the basic pricing.

This is a pretty good tool to use for filling out, signing, sending, and working on high school scholarships! you can open .pdf files right on the program and fill them out and even sign them and email them to the recipient. The only downside is the cost, its kind of ridiculous in price.

What do you like best?
The ease of filling in forms and quickly.
What do you dislike?
Nothing except that when I print a doc, the Print button is at the bottom of window and I can't move it up so I have to click the very tip of the box that says print. - This could be my computer problem too but is weird and that just started about 6 months ago.
What problems are you solving with the product? What benefits have you realized?

What do you like best? GREAT to use, has lots of options and you can upload almost anything! What do you dislike? I wish that there were more options, like adding icons, or company stamps. I also have found sometimes when I download it there are lines that run through it, very frustrating when it took like an hour to manipulate a document, and it won't upload without random lines. What problems is the product solving and how is that benefiting you? Specifically AIA forms for commercial contracting, such a great tool!
