In the Emergency Response Management package, key features for Volunteer Management include the automatic update of volunteer counts and the ability for volunteers to engage actively with projects. When volunteer shifts are canceled, the system automatically adjusts the count of registered volunteers and the number of volunteers needed, ensuring accurate and real-time management of volunteer resources. Additionally, volunteers have the capability to sign up for projects and log their activity time, fostering an interactive and accountable volunteering environment. These features support effective and efficient volunteer coordination during emergency response efforts.
