Hiya Ed,
If you're trying to figure out "how" to export the form to use with WordPress use the File option on the top menu and choose Export and then Manual and then from there do what it says to do. I'm not sure of the exact locations the files need to be for a WordPress page, but that's how you export the form to use on other servers besides S-Drive. I'm hoping a future release will actually put an Export Button or show both options on the Publish Button to choose from instead of looking as if it's only for S-Drive as we've had quite a few ask about how to do this.
If you need more info on how to add it to the actual WordPress, then I can't help there sorry, I don't use WordPress or CMS's at this time.
