# Registration, approval and capacity

> Control what guests are asked, whether you approve them, how many can come, and what the public page reveals about who is attending.

## The registration form

Under **Registration experience > Registration form**, choose what information guests provide when they register. These questions are specific to event registration and are separate from the booking questions used on Links.

## Require approval

Under **Policies > Privacy and security**, turn on **Requires confirmation** so registrations wait for you to approve them before they are confirmed.

Guests waiting for approval see **Pending approval**, and the public registration button reads **Request to join**.

## Capacity and waitlist

Under **Attendance > Settings**:

* **Limit capacity** with an **Available spots** number, up to 100,000. Capacity is unlimited when the limit is off.
* **Waitlist** lets guests join a waitlist once the event is full.

A few rules are worth knowing before you set these:

* The waitlist is only available together with a capacity limit. Turning capacity off clears the waitlist.
* The waitlist is not available on paid events. Charging for an event means turning approval and the waitlist off first. See [Paid events with Cal Pay](/help/events/paid-events).

When the event is full, the public page shows **Join waitlist** if the waitlist is on, or **Sold out** if it is not.

## Who guests can see

Also under **Policies > Privacy and security**:

* **Hide host's email** removes it from the event page, the emails, and the calendar events.
* **Public guests** controls whether visitors see who is coming. This setting is owner-only, so a co-host cannot change it.

**Public guests** has three options:

| Option             | What visitors see                                                 |
| ------------------ | ----------------------------------------------------------------- |
| Don't show guests  | Nothing about who is attending                                    |
| Show guest names   | A public list of confirmed guests. Guests can hide their own name |
| Show a going count | "N people are going!" with no names                               |

The public list shows names and initials only, never emails or photos. A guest who hides their name still counts as going, and the going count excludes anyone who answered **Not going**.
