Here is a list of what you need to do

• Be friendly in most games.
  
• Accept game requests and don't just ignore them.
  
• Don't complain that your computer is bad, (some cases may be accepted)
  
• When you play a game and don't like it say it, (you have a choice to say i don't want to play)
  
• You can do whatever you want but destroying for other people are not good.
