    When you’re a student, you deal with PDFs a lot… Newsletters, various worksheets, official forms you need to fill in and sign, etc… To me, filling out a PDF form used to be among the trickiest and most time-consuming things ever. But then a friend of mine introduced me to PDFLiner, and oh my God, my life has changed since then. It’s easy to use and has so many great features. Just awesome, I love it!
