Description

👋Hello, welcome to Jackhammer Studios! Join the group for free RANK in the game!

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

Membership history

Growth

3 measurements spanning 68 days, net -3. 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 707–710 and does not start at zero.
