## Recent Work: BlackMuralBulkSMS Project`
`
I've been actively working on the BlackMuralBulkSMS project, focusing on the following files and tasks:

*   **`client/send_bulk_sms.php`**:
    *   Implemented template variable substitution.
    *   Corrected PHP syntax errors.
*   **`model/send_bulk_sms.php`**:
    *   Corrected `security` function usage.
    *   Fixed PHP syntax and logic issues (e.g., duplicate code, incorrect sender type handling).
    *   Implemented message personalization with contact data and custom fields.
*   **`client/sms_history.php`**:
    *   Refactored message display to use data attributes for robustness.
    *   Fixed conditional rendering logic.
