• Who moderates this community?
  The short answer is: you. This website is moderated by the users. Points system allows users to earn rights to perform a variety of moderation tasks.
• How does point system work?
  When a question or answer is voted up, the user who posted it will gain points. These points serve as a rough measure of the community trust in that person. Various moderation tasks are gradually assigned to the users based on those points.
  
  For example, if you ask an interesting question or useful answer, it will likely be voted up. On the other hand if the question is poorly-worded or the answer is misleading - it will likely be voted down. Each up vote on a question will generate 1 points, whereas each vote against will subtract 1 points. The following table lists points gained per activity:

• How to change my picture (gravatar), and what is gravatar?
  The picture that appears in user profiles is called a gravatar, which means globally recognized avatar.
  
  Here is how it works: You upload your picture (or your favorite alter ego image) to the website gravatar.com from where we later retrieve your image using a cryptographic key based on your email address.
  
  This way all the websites you trust can show your image next to your posts and your email address remains private.
  
  Please personalize your account with an image - just register at gravatar.com (just please be sure to use the same email address that you used to register with us). The default gray image is generated automatically.
