Facebook simplifies guest management. Head to your event page and click on "See All" next to the "Going," "Interested," and "Invited" sections to view your RSVPs. You can also use the "Invite" button to add or uninvite friends. If your event has a large guest list, the search bar comes in handy for finding specific names. Plus, Facebook sends notifications for RSVPs, keeping you informed in real-time. This feature ensures you stay organised, know who to expect, and can plan accordingly for a successful and well-attended event on Facebook.
