[meta] Expand FAQ "What should I avoid in my answers?"
This section of the FAQ should be expanded to make clear that:
- Answers should not add or expand questions. Instead either edit the question edit or add a question 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 question comment indication "Possible duplicate of...". However, it's ok 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 complementary to answer, referring sources or additional reading.
