Description

Currently there isn’t anything happening or gonna happen. You could say this is a hang out group since that’s what it basically is. I had ideas for this group but it’s scrapped. For the people who were hopping that something would happen, I apologize. But feel free to stay.

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

Membership history

Growth

2 measurements spanning 27 days, net -1. 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 149–150 and does not start at zero.
