The page shows sign-ups for the last 30 days, 90 days, 12 months or all time. Days have a column each with a 7-day average line; longer ranges use weeks or months. A second chart shows total accounts. Point at a chart or use the arrow keys to read a date's figures, or open the table of every figure.
Dates follow the viewer's time zone. Deleted accounts are not counted. The page is not linked from the menu: it opens only at its private address, for website admins and one other chosen account.
