How can I create a signature box where form users can draw in their signature instead of type it?

Hey All,

Currently when I create a signature form field it only lets me type in the field. I am unsure if this is an error or is some form of digital signature. Regardless, I would prefer if when a user clicked this signature box they could draw in their signature instead of typing it so it looked like the user was signing a document by hand.  If I am using acrobat, I can use the "fill and sign" mode to sign boxes. Unfortunately, when I email this form to someone else, who does not have acrobat, they are not able to.

Warmly,

Jesse
