Growth

6 measurements spanning 16 days, net +28. 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 1,559–1,595 and does not start at zero.

A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the member count as measured 23 August 2026 — this entry's latest reading, not the date you are reading this.
