When you ask a question, show your effort, provide all the details that will help someone to help you and be precise.

When you answer a question, don't just paste your code. Your answers will be much better when you explain why your code is doing what it does and how it achieves the asker's goal. It makes it a whole lot easier to follow along. As it is I am much more inclined to up-vote answers that have explanatory text about what the code is doing and why it is written as it is.
