History

During its first two years or so, the organization had a volunteer network of around 25 people from the effective altruism and rationality communities, with a presence on about a dozen US college campuses. Kelsey Piper was an early member. Afterward, activity declined, and the chapters were transferred to LEAN.^[2]
