Does every attendee get their own link?
Yes. Rather than one public link, each registered attendee is issued a private, secure join link, so you control who reaches the session and can see whose seat is still empty.
Can I cap the numbers?
You set the capacity when you configure registration, and sign-ups count against it, so the room fills to the number you intended and you can close registration once it is full.
Is this the same as a party RSVP?
No, and that difference is the point. A workshop uses real registration, a name and email and a personal join link, whereas parties use a simple reply button against your guest list.
Can I take payment for seats?
This collects registrations; taking payment for seats is not what it does. If you need paid ticketing, that is a separate decision, and it is not offered on this page.
Will people remember to turn up?
Email reminders go out before the session to the people who registered, with their join link in front of them, which is what keeps a room fuller than a calendar invite alone.
Can I see how many seats are still open?
Registrations count against the capacity you set, and the running number sits on the attendee list you read. That is the guest list doing its job, not a separate reporting dashboard bolted on top.
