Although I feel this is really unnecessary, but just as a reminder: 

  * If possible, please turn on your webcam and voice when you enter spatial chat. 
  * When you enter a group, please say hi to other group members, and introduce yourself if there are some members. 
  * When you leave a group, please say goodbye to the other members, don't just disappear. You can try [[https://www.youtube.com/watch?v=Qy9_lfjQopU | this]], for example.
