Membership history

Growth

65 measurements spanning 57 days, net +299. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 2,538–2,928 and does not start at zero.
