Membership history
Growth
Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
| Measured (UTC) | Members | Change |
|---|---|---|
| 13 Aug 2026, 20:55 | 11 | first reading |
Daily: the last measured count of each UTC day. Days with no new reading have no point. The full per-reading record is in the CSV and JSON downloads below.
