A Scroll Party is a way to run your online parties off of social media. It includes a page to RSVP that includes a form to collect guest information (name, email, phone number, etc.) and a Scroll Party page that includes all the information you would normally post and include in your online party. Party guests get automatically taken to the Scroll Party page to view the content after filling out the RSVP form.
The video below walks through the setup of a scroll party on your Oh My, Hi site.
