## Usage

### Displaying a Form

Use the shortcode to display a registration form on any page or post:

```
[go_form id=1]
```

Replace `1` with your form ID. Find form IDs in the admin settings page.

### Admin Settings

Navigate to **Go Form** in the WordPress admin menu to:

- **Create Forms** - Add new registration forms
- **Manage Forms** - View all forms with their shortcodes
- **View Entries** - See all submissions for a form
- **Delete Entries** - Remove individual registrations
- **Delete Forms** - Remove a form and all its entries (cannot delete default form)
- **Export Data** - Download entries in various tournament formats

Players can click the "Search EGD" button on the frontend form to look up their information in the European Go Database. This auto-fills:
- First Name
