I'm sure this question has been asked before. I've created a form containing various fields using Adobe Designer, and am now opening it using Adobe Reader. I'm well aware that you can't save info you type into any fields while using Reader, however at the bottom of the form I've created is an electronic signature field I've also created. I just want to be able to click on that while using Reader and be able to sign the form electronically, like I was using Acrobat. I know I should probably invest in that LiveCycle Reader Extensions stuff, but I'm also aware that could cost me a lot of money. Is there any possible way I can get that signature field to work in Reader? Some plug-in I could download? I need to know ASAP, I've go a project to do at work and could really use the help!
