Who moderates this community?

The short answer is: you. This website is moderated by the users. Karma system allows users to earn rights to perform a variety of moderation tasks

How does the karma system work?

When a question or answer is upvoted, the user who posted them will gain some points, which are called "karma points". These points serve as a rough measure of the community trust to him/her. Various moderation tasks are gradually assigned to the users based on those points.

For example, if you ask an interesting question or give a helpful answer, your input will be upvoted. On the other hand if the answer is misleading - it will be downvoted. Each vote in favor will generate 15 points, each vote against will subtract 1 points. There is a limit of 200 points that can be accumulated per question or answer. The table below explains karma requirements for each type of moderation task.

  • add comments -> 0
  • delete comments -> 400
  • close own questions -> 60
  • reopen own questions -> 120
  • retag questions -> 150
  • edit any answer -> 400
  • open any closed question -> 600
  • delete any comment -> 400

What if I don't get an answer?

Well, this system is powered by the community. You must respect that other people spend their time to answer your questions—sometimes the community is not willing to spent time for your question.

The best thing you can do to avoid this, is to provide a well written question. Make sure you provide all required information, but explain your problem as short and precise as possible.

Here are some more guidelines:

  • Format your post. Use the Markdown syntax that is described in the left column.
  • Reduce all your code to the smallest possible fragment that still reproduces your problem.
  • Make sure all your code can be copy&pasted as is. E.g., remove the "SQL>" prompt and similar noise.

Well, by a lucky coincidence, the operator of this service is consultant on that topic :)
