Computer-mediated communications, in particular listservs, can be powerful tools for creating social change--namely, shifting our food system to a more healthy, just, and localised model. They do this by creating the conditions--collaborations, interaction, self-reflection, and personal empowerment--that cultivate distributed leadership. In this article, we will show how the listserv hosted by the Farmers Market Coalition (FMC), a US-based non-profit organisation, acts as an important venue for involvement in a community of practice, through which informal learning and the formation of distributed leadership takes place. The learning that takes place through this listserv can be seen as part of a transformative process that empowers participants to make change and builds unity across the movement.
