This program is a wonderful tool for those in need of completing documents with step by step instructions & returning later if need be. I appreciate those who assist with making this free program. It is a real Blessing also to those such as myself who cannot afford an attorney with knowing that forms are up to date & accurate. Thank you

There are things I still can't figure but overall, I am getting the hang of it and it seems fine. It takes a while to go between pages but that could be on my end.

This product is fantastic! It is an easier way to scan in documents that need information changed often. We have made them templates. It allows us to change already printed documents and keep the professional look. It is an easier way to share templates with others on the team. The ease of use and the price. The software is almost intuitive, so that almost anyone can use it without spending a lot of time. It has all the functions that get the job done. The printing of documents requires having adobe for us. We have found that printing straight from the website, often does not print in full size. We have to save as PDF and then print. You can make it work, but it takes longer.

The fill in is with text boxes like in word. That works well. It worked well. Not as good as a PDF document that already has input fields but much better than printing the PDF document and filling it in by hand,

Thank you so much for the super prompt reply! I had somehow removed the date stamp from my digital signature and I could not figure out how to get it back on. Turns out it was a pretty simple fix (doh!). Kara responded super fast to my cry for help. She provided written instructions as well as a screenshot (very helpful!). My date stamp is back on. :)
