Description

Long live J.K. Rowling! She created our house, after all. Slytherins pride themselves on being ambitious and cunning. If thats says "you," then this is your group! If you are active on the group and you seem to be a very ambitious and Slytherin-like person, then you will get promoted! Who knows, you might become Head Student. :)

Membership history

Growth

2 measurements spanning 33 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 26–27 and does not start at zero.
