+# Email Prompt on Event Registration
+
+## Overview
+
+When users without a registered email address attempt to sign up for an event, they are now prompted to add an email address. This ensures they can receive notifications about event changes or cancellations.
+
+## Implementation
+
+### New Component
+
+**`src/components/event/EmailPromptModal.tsx`**
+- Modal that appears when a user without an email tries to register for an event
+- Provides two options:
+ 1. "Add Email Address" - Navigates to user profile page
+ 2. "Continue Without Email" - Proceeds with registration anyway
+
+### Modified Files
+
+**`src/pages/EventsPage.tsx`**
+- Added email check in `handleRegister` function
+- Checks if user has `primaryEmailAddress` before registration
+- Shows EmailPromptModal if no email is found
+- Added navigation to user profile page for email management
+- Maintains pending event ID to complete registration after user decision
+
+**`src/components/event/index.ts`**
+- Added export for `EmailPromptModal`
+
+## User Flow
+
+1. User clicks "Register" or "Quick Register" on an event
+2. System checks if user has an email address registered
+3. If no email:
+ - EmailPromptModal appears
+ - User can choose to:
+ - Add email (redirected to profile page)
+ - Continue without email (registration proceeds)
+4. If email exists:
+ - Registration proceeds normally
+
+## Benefits
+
+- Encourages users to add email addresses for better communication
+- Non-blocking - users can still register without email
+- Clear messaging about why email is beneficial
+- Seamless integration with existing registration flow
+
+## Technical Details
+
+- Uses Clerk's `user.primaryEmailAddress?.emailAddress` to check for email
+- Modal is shown before API call to register
+- Pending event ID is stored in state during modal interaction
+- Registration completes after user makes a choice
