That i was able to fix and remove… That i was able to fix and remove unwanted documents to send just what i needed. The fact that I can fax without having a big machine to do, matter of fact that is one of the reasons that I decided to use pdfFiller. You make filling out important documents easy and able to sign by uploading just a picture of the signature needed. However you could make it easier to be able to create a fax sheet more personal. The one on the website is okay but not personal enough. Maybe I will think about doing the annual thing let's just see what more I can learn to do with your program. thank you for making it so easy to send important documents from the comfort of my home office without having to pay someone else to fax for me
