I have been using this site for 10 minutes, I really cannot give a good assessment. I do believe that a users manual should be more accessible from the home page so you can review the user guide while using the form filler.

Great experience for me since I'm preparing from a remote location in the mountains using the e-signature feature sending to legal services for filing.

The program interface is OK but it could be a little more iterative. A form I was completing for the TSP TP77 and the TP76 did not place the letters and numbers (characters) in the exact center of each box making the document a little harder to read. I know this for sure because I have completed the same document using TSP website filler with the document are available. This would be easy for the company to fix this but they check their forms before making them available. But the overall online forms filler program works well and saves completed forms easily and has a generous library.

Great, however, could be improved with quicker selection of initialing or signing. Maybe a way of clicking at the point of initialing and pasting without having to select each time you have to initial as slow if having to do lots of initialing.
