Originally The Unofficial #SaveCosmo Group on ROBLOX Mostly inactive since 2022 Archived

Written by the group; not a statement by this register.

Membership history

Growth

3 measurements spanning 47 days. 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 499–500 and does not start at zero.
