Recruiting and managing volunteers is really straightforward. Set up a volunteer sign-up page and begin encouraging your supporters to go there. A volunteer button linked to your volunteer sign-up page will appear on your supporter navigation bar so people will see that there is a need for volunteers practically everywhere on your site. On the actual sign-up page you can ask for different volunteer roles that people can choose from, such as canvasser, event volunteer, letter writing, or office manager.
Once your volunteers are signed up, you can keep them active by creating a calendar page listing multiple volunteer events. Use your database to log contacts with your volunteers, so you know who hasn't helped out in a while. On your broadcaster page you can stay in touch with your volunteers by sending them blast emails, tweeting, and updating your status on Facebook. You can link your events to Facebook events, making them one in the same so volunteers can RSVP from there. They can even RSVP for your events via text.
