Once you have defined your volunteer roles and expectations, you can start recruiting volunteers. You can use various channels, such as social media, email, word-of-mouth, or online platforms, to reach out to potential volunteers. You can also partner with local organizations, schools, or groups that share your mission or vision. When recruiting volunteers, make sure you communicate the benefits and expectations of volunteering clearly and honestly. You can also use an application form or an interview process to screen and select the best volunteers for your conference. After you have recruited your volunteers, you need to train them properly. You can use online or offline methods, such as webinars, workshops, manuals, or videos, to provide them with the necessary information and skills. You should also introduce them to your conference goals, values, and policies, as well as the staff and other volunteers they will work with.
