Requires:

• The Events Calendar Plugin (for listing events)
• Gravity Forms
• Gravity Forms Strip integration

To install this, download the .json file and import it into your Gravity Forms install. This will create the RSVP form. Embed this form into an Events Calendar (From Modern Tribe) event, and then you can charge for an event through Gravity Forms w/ Stripe.
