# Member Classification Script

Classifies members from an email list into three categories:
- **not-in-good-standing**: Status is not "Member in Good Standing" (including empty values)
- **existing-member**: In good standing and already in the member database
- **new-member**: In good standing but not yet in the database

## Requirements

Python 3.6+ (no external dependencies)

## Usage

### Basic Usage
```bash
python classify_members.py
```

Uses default files: `AllMembersEmails-20FEB2026.csv` and `nnjdsamembers.csv`

### Custom Files
```bash
python classify_members.py --all-members your-file.csv --member-db your-db.csv
```

## Input Files

**All Members File**: CSV with columns `email`, `membership_status`, `list_date`

**Member Database File**: CSV with "Email address" column (first descriptive line is skipped)

## Output

Creates a folder named after the date extracted from the input filename (e.g., `20FEB2026/`) containing:
- `{DATE}_not-in-good-standing.csv`
- `{DATE}_existing-member.csv`
- `{DATE}_new-member.csv`

All original columns are preserved in the output files.
