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:)

For my very first experience I was a little surprised it wasn't free when I already am an Adobe Pro in the Cloud user and pay monthly for that, but oh well.

Great concept - I can finally share my documents with people. Although it would be good to be able to switch things off like the steps clip note as on some of my pages there are 300+ fields to fill in!

For a new customer who has only used this program for a short time, It's a bit confusing to find all the necessary information. I am learning, but it's taken some navigation, and I haven't used the help line, because I don't even know the right questions to ask.

A great Program Its a good program, but it takes a few minutes to get use to the actual text placement for your fill in. I did not try the signature feature. I will continue to use this program. I'll use it more often as I get use to it.

If I had the option to put 100 stars, I would. This product is fantastic. There are small issues with reformatting, but I think the user can get over that.
