LIKED THE ABILITY TO SAVE AND PRINT BUT IT TOOK SEVERAL TRIAL AND ERROR EXPERIENCES TO FIGURE OUT THE PROCESS. SOMEONE WITH VERY LITTLE COMPUTER EXPERIENCE WOULD FIND THIS FRUSTRATING

Quite simple and handy to fill. I would have preferred using my own signature on the completed form but I had difficulty loading an image of my signature.
