This is a very convenient service, I loved that I could prepare my documents and save them to come back for any necessary changes. Also, how nice it is to get all the forms I need in one spot without having to search around on different websites. Thumbs up from me:)

Love this program! I am new with it, but it makes my paralegal position ( I do public benefits advocacy) much easier in filling out forms that are not fillable on the Social Security website.

It was pretty easy to use except when you hit the next tab it would take me to the text box to type but it would not allow me to type until I moved my mouse to that location and click. It would be easier if it would allow you to type in the box it moved you to so you don't have to keep going back and forth to the mouse. Also some boxes when completed there was not an option to click "next.

I really like it so far. The snap to grid text editing is fantastic. The cloud options and email sync are perfect. Nice job. The UI is almost exactly like my Neat scanner software so it's very intuitive.

I really like the program; however, when I save I get logged out. I have not been successful at using any form except the Offer to Purchase. I need addendums.

I love the program. The smart folder...not a fan. Do not like that we have to "tag" them and I would prefer to just make and name my own folders and move PDF docs into them as I wish (like windows mail).
