One of the keys to using RSVPMaker effectively is taking advantage of event templates. Like the rest of RSVPMaker, the templates feature has been updated for the new Gutenberg editor.
Templates allow you to create one or many events that follow a regular schedule and that share some basic details like meeting location and who to contact with questions.

Think of it like the relationship between the cookie and the cookie cutter, where you can stamp out one or many cookies that start out the same, but you still have the option of decorating them all differently, with details specific to a particular event date.
On the other hand, if you’ve created many placeholder events based on your template and you change the template (say, because your meeting location has changed) — you can update those related events. You can update them all, or update them selectively (if you don’t want to overwrite information you’ve added for a specific event date).
