 ### Display Format
 
-For display purposes, usernames are truncated to fit screen constraits:
-- BBS name: First 2 characters
-- Username: Up to 8 characters
-- Format: `BB:username`
+**Storage vs Display**: The database stores the full username format (`Forum3270:moshix`), but the chat interface displays a truncated version to fit screen constraits.
+
+**Display Truncation Rules**:
+- BBS name: Truncated to first 2 characters
+- Username: Truncated to maximum 8 characters  
+- Display format: `BB:username`
 
 **Examples**:
-- `Forum3270:moshix` → `Fo:moshix`
-- `RetroNet:john_doe` → `Re:john_doe`
+- **Stored**: `Forum3270:moshix` → **Displayed**: `Fo:moshix`
+- **Stored**: `RetroNet:john_doe` → **Displayed**: `Re:john_doe`
+- **Stored**: `ClassicBBS:administrator` → **Displayed**: `Cl:administ`
+
+**Important**: When reading from teh database, you get teh full username. When displaying in chat history, the system automatically truncates for screen formatting.
+
+**Helper Function for Display Formatting**:
+```python
+def format_username_for_display(full_username):
+    """Convert 'Forum3270:moshix' to 'Fo:moshix' for display"""
+    parts = full_username.split(':')
+    if len(parts) != 2:
+        return full_username[:9]  # Fallback for invalid format
+    
+    bbs_name, username = parts
+    # Truncate BBS name to 2 chars, username to 8 chars
+    truncated_bbs = bbs_name[:2]
+    truncated_user = username[:8]
+
