Answers should not add or expand questions. Instead, either edit the question or add a comment.

Answers should not comment other answers. Instead add a comment on the other answers.

Answers shouldn't just point to other questions.Instead add a comment indicating "Possible duplicate of...". However, it's fine to include links to other questions or answers providing relevant additional information.

Answers shouldn't just provide a link a solution. Instead provide the solution description text in your answer, even if it's just a copy/paste. Links are welcome, but should be complementary to answer, referring sources or additional reading.

Answers should not start debates This community Q&A is not a discussion group. Please avoid holding debates in your answers as they tend to dilute the essence of questions and answers. For brief discussions please use commenting facility.

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 10 points, each vote against will subtract 2 points. There is a limit of 200 points that can be accumulated for a question or answer per day. The table given at the end explains reputation point requirements for each type of moderation task.
