- They can still be in other groups
- Can be re-added later

### Group Edits Before Start Only
- Once you start a group, details are locked
- Check everything carefully before starting
- Members and draws can still be edited after start

---

## 🔍 Member ID System

### Two Types of IDs

**1. Member Number** (Human-friendly)
- Format: #1, #2, #3, #4...
- Display: Large purple badge
- Usage: Verbal communication, receipts, WhatsApp
- Example: "Member #5"

**2. UUID** (Technical)
- Format: c5530367-7110-4914-bfa6-f03818dedeb2
- Display: Hidden by default (show in edit dialog)
- Usage: Database operations, API calls
- Example: For technical support only

**Best Practice**: 
- Show users the member number (#5)
- Keep UUID for backend operations
