Take a look at Navigating RSVPMaker: Event Posts, Options, Messages and Forms for a summary of the screens for setting options and customizing confirmation messages, reminder messages, and the RSVP Form. Some of these directions are specific to using RSVPMaker with the Gutenberg editor.
Here’s an overview video tutorial that covers creating events, customizing the registration form and setting parameters such as pricing when you’re charging for an event and collecting money via PayPal or Stripe:
NOTE: Some of the screenshots in the older documentation linked to below are outdated. As part of a series of changes related to WordPress 5.0 and the new WordPress “Gutenberg” editor, many options that were previously displayed below the content editing area are now on a separate Event Options screen. The functionality hasn’t necessarily changed, just where you’ll find it. New functionality includes a form editor based on Gutenberg.
I’ve been adding documentation a little at a time, through the blog. Let me know what still needs to be explained better.
