I found it relatively easy to use, it would be nice if it had an undo selection. And getting the right size font was not easy. Had to wait for print out to see.

At first I was a little concerned. Difficult experience in the past. More business are utilizing e-sign, Do c-section and Right signature. Nice that I can utilize this program with compatible other programs
