The MEC Waiting List Addon seems quite robust, offering features for managing waiting lists when tickets are sold out. Here's a breakdown of its functionalities and how to use it:

Installation and Setup:

1. Installation: Upload the ZIP file via WordPress Dashboard > Plugins > Add New and activate it after ensuring MEC is fully installed.
2. Configuration: Access MEC Settings > Booking > Waiting to set up Waiting List Addon functionalities.

Features and Configuration:

• Total Waiting Limit: Define the maximum number of waiting list spots available. Leave it empty for unlimited waiting.
• User Email Verification: Set whether user email submission requires default verification or send a verification link to the user's email.
• Auto-Confirmation: Enable/disable auto-confirmation for waiting submissions without admin review.
• Attendee Info Sharing: Choose whether to apply the first attendee's info to all purchased waiting by the same user or keep individual attendee info.
• Verify and Cancel Page Setup: Create a dedicated page for waiting list notifications using the [waiting_notif_page] shortcode.
• Custom Waiting List Form: Modify the waiting list form using the form builder in MEC Settings, particularly for specific events if needed.

Email Management:

• Notifications Configuration: Manage outgoing emails through MEC Settings > Notifications. Customize Waiting Verification and Waiting Confirmation emails using placeholders and HTML templates.

Important Considerations:

• Payment Method: The waiting list is registered as 'Pay Locally,' ensuring payment collection if tickets become available.
• Verification and Confirmation: Only verified and confirmed waiting list participants can secure reservations based on their queue priority.
• Manual Confirmation: Confirmation is usually a manual process, unless the Auto-Confirm option is enabled.
• Cancellation Handling: Users can cancel their reservations using the placeholder in the confirmation email, updating their status accordingly.

User Interaction:

• Verification Email Placeholder: Allows updating reservation status if Auto Verify is disabled.
• Cancellation Mechanism: Users can cancel their reservations by clicking on the link provided in the confirmation email.

The addon offers a comprehensive solution for managing waiting lists, verifying and confirming participants, and handling email notifications, ensuring a smoother ticketing experience when events are sold out.
