Was a little cumbersome at first, but was able to figure out on own which says a lot about a computer program minus an instruction booklet. Yeah, I'm a little on the geek side.

I love this tool I love this tool. I shared it with my mom who still has to fax things and I did not want her leaving her home to fax at other businesses. I think a video on how to create more fillable boxes would be helpful. Although I figured it out, it took me about 30 minutes. I can imagine for even less tech savvy people it could take longer.
