To add multiple jotforms to the Thunderpenny Static Html app, you can check out our ideo instructions here: http://www.screencast.com/t/ydiyrClDRIG. And see our written tutorial below. :)

From the main jotform.com menu, after you’ve created your form, select: Embed form > secure form > Embed > copy this embed code 

Now in the Thunderpenny Static Html App, paste in your code, preview, and if it looks good, save.  

To add a second form, go back to jotform.com, and select: My Forms > Create Form.

Now create your form, and follow the same steps for getting the secure embed code. In the Thunderpenny Static Html app, paste the secure embed code above or below the previous jotform embed code. Preview, then Save. Voilà!
