While I'm not 100% certain we have the tools as a search showed it as WebAssist Free Tools, I got as far as using what I believe was the form builder but could not seem to find where the email options were. Attached is the page I was working on.
I am also following instructions from http://www.webassist.com/tutorials/Customize-form-elements-in-your-form-generated-emails but am stuck on the section where it's telling me "In the file browser, expand webassist > email > templates." which I can't seem to locate.
