PDFFiller responded to my concerns and moved me from inexperienced to competent user status. They promote a feature that pulls PDF files from your email to your account - looking forward to learning how that works.

The service is great and has come in handy in ways I had not expected. However, you lose 2 stars for my initial experience of first being asked to to pay, by a pop-up, to see a form that was submitted and then after paying being told by another pop-up that I need to upgrade to a more expensive plan. The first pop-up should have presented the correct plan. Felt a little like a bait and switch. But I gave you back one star due to the fact that support was able to fix the problem, quickly.

I'm impressed with PDFfiller but I think there could be more options of background colours of the textbox, including different shades within each color.
