# Custom Signup Fields

## Who this is for

Authors collecting structured information from readers.

## Overview

Defines the questions readers see on signup forms, with answers stored on their profile for filtering and personalization.

## How it works

### Two scopes

* **Workspace-level fields** — applied across all signups (mailing list, audience join)
* **Book-level fields** — specific to one book (used on its ARC signup form and shown on Book Readers)

### Field types

* Short text
* Number
* Boolean (yes/no checkbox)
* Date
* Single-select dropdown
* Multi-select (with optional "Allow other" custom value)

### Per-field options

* Label, internal key, description
* Required or optional
* Sort order
* Active toggle (hide without deleting)
* Placeholder text
* Select options (for select/multi-select)

### Visibility flags

* **Workspace fields:** show in audience table, show in public signup form
* **Book fields:** show in book readers table, show in public signup form

### Where fields appear

* ARC signup form (book-level fields)
* Mailing list join page (workspace-level fields)
* Audience join page (workspace-level fields)
* Reader profile (always editable)
* Book Readers table (book-level fields)
* CSV import (any active workspace field becomes a recognized column)

### Example fields authors create

* "How did you hear about me?"
* "Do you post reviews on Goodreads, Amazon, or both?"
* "Preferred ebook format"
* "Have you read Book 1?" (book-level, for series ARC eligibility)
