MEC Waiting List is a handy WordPress plugin that works alongside the Modern Events Calendar, letting you manage event registration overflow with ease. It's perfect for event organisers, venue managers, and community admins who regularly deal with fully booked events. When capacity is reached, visitors can join a waiting list and receive automated email notifications if a spot opens up. The built-in queue management and WooCommerce compatibility make it a smart choice for keeping attendees engaged and your events running smoothly.
