"So where do I find those people?"
The question came from an organiser who had watched his hall fill up twice. The waiting list was doing its job — people signed up, tickets freed up, the emails went out — but he could not see anywhere who was waiting. Which is exactly what you want to know when you are weighing up an extra performance.
The honest answer was: nowhere. The waiting list was a machine without a window in it. That window is in now.
The Waiting list tab
Open an event in the organiser panel and next to Orders and Guest list you will find a Waiting list tab. It shows the queue per ticket type, in order of sign-up — first to sign up, top of the list.

Each row shows four things: the position in the queue, the name, the sign-up moment and the status. That status is either "Waiting" or "Emailed on ‹date›". Anyone who has already been notified no longer counts towards the queue: that row gets a dash instead of a number, and the next person waiting is back at position 1. That way "position 3" keeps meaning what it says — there are three people ahead of you.
Top right of each ticket type sits the counter: 24 people waiting. That is the number that matters when you have to decide whether to schedule a second night.
How it works underneath
For anyone not using the waiting list yet, here is the short version.
When a ticket type sells out, the buy button on your event page turns into "Add me to the waiting list". The visitor leaves a name and an email address. Nothing else — no payment, no account.

Every fifteen minutes MijnEvent checks each ticket type for freed-up capacity — through a cancellation, a refund, or because you raised the capacity yourself. If there is room, an email goes to the first five on the list, in order of sign-up, and never to more people than there are seats. Anyone who has been notified is not notified again.
That email goes out in the visitor's own language and points at your event page, where they buy their ticket the normal way.
The two buttons
There are two at the top of the tab.
Email the waiting list now runs exactly the same round as the scheduled task, but immediately. Useful when you have just raised the capacity and do not want to wait, or when you promised someone on the phone that word would go out today. The rules still apply: never more messages than there are seats.
Export hands you the list as a CSV with the full email addresses in it — because an export exists precisely so you can get in touch. The file arrives as an encrypted zip and the password comes separately by email. That permission can be granted separately to team members, just like the other exports containing personal data.
And each row has a remove action. For someone you already helped outside the platform, or who asks to be taken off. Everyone behind them moves up a place.
How many people are waiting for this ticket type?
The Ticket types tab now answers that too, without a click. Underneath the capacity bar sits the number of people waiting — and for a sold-out type that is the most interesting figure on the screen.

Privacy: masked, unless
A waiting list is a list of personal data belonging to people who have not bought anything from you yet. We treat it the way we treat your visitors: the email address appears masked.
Need the full address? Click "Show email address". That is entirely fine — but it is recorded in your activity log, with who did it and when. Not to look over your shoulder; so that you can show it later if anyone asks.
The list is only visible to team members with the events permission, and anyone whose permissions are limited to certain events only sees the waiting lists of those events.
Switching the waiting list off
The waiting list is on by default for every new event. That is the setting you want in almost every case: it costs you nothing and it hands you a list of people who would love to come.
But some events do not suit it. A private evening that is full and stays full. A performance where you know for certain nothing will free up, and a waiting list would only raise false hope. In that case, untick it under Edit event.

With it off, your event page simply says "Sold out" and the sign-up button disappears. Existing sign-ups stay exactly where they are — nobody's data is thrown away — but no messages go out while the list is off. The panel warns you about that if people are still waiting, so you do not do it by accident.
What comes next
The next step is a personal buy link with an expiry time: whoever gets notified holds their place for a number of hours and is the only one who can buy through that link. That turns it into "it is your turn" instead of "be quick". Today's window into the list is needed for that anyway — and stands on its own, because the question this all started with now has an answer.
