Tegen wil en dank, desalniettemin heeft het toch een prettige samenwerking opgeleverd. Velen inmiddels dankzij jou in het zonnetje gezet en hun jubileumster mochten ontvangen, waarvoor deze ster een klein gebaar is. MVG, Arch (Overleg) 7 mei 2019 20:58 (CEST)

from the same person (as Samenwerkingsster) on 201809090917
10 jaar actief Deze ster is voor mensen die zich al 10 jaar of langer inzetten voor Wikipedia.
U bent al meer dan 10 jaar actief, dus deze ster heeft u verdiend!
from Ellywa on Sterrendag 2019 (i.e. Day of the Barnstars) at Dutch language Wikipedia 201912311227
Sterrendag! Het is vandaag sterrendag, de dag waarop we elkaar nog even extra bedanken voor een jaar vol enthousiasme en prachtige bijdragen. Ik wil jou vooral bedanken voor de sterren die je zelf uitdeelt aan mensen die een jubileum vieren op Wikipedia. Elly (overleg) 31 dec 2019 12:27 (CET)



famous people
  • if you can't handle me at my worst, then you sure as hell don't deserve me at my best.
  • A veteran - whether Active Duty, Retired, National Guard or Reserve - is someone who, at one point in their life, wrote a blank check made payable to "The United States of America", for an amount of "up to and including my life." - That is Honor, and there are way too many people in this country who no longer understand it.

seen me in real life?
