Just starting to use this - think it will work for me. Sometimes find it awkward to intuit what to do, so would really benefit from a webinar if offered free.

It's been very good working with PDF Filler. Makes saving forms so much easier. I only have one complaint. When it comes to dates, I usually need to write it as year-month-day; but PDF Filler is already programmed as day-month-year so I have to keep on erasing dates and fill it out by hand, which is annoying.

Hard to get used to, and probably a lot of features we are not taking advantage of for lack of know-how, but very reliable and handy. We mostly use it to send for signature.

PdfFiller = The Filler of all PDF filling needs! A fine program, useful, optimal, and perfect for what it's for. Ease of use, its incredibly easy and fast for the task. Could be cleaned up a bit. Lots of options that are a bit messy.
