What are your quality standards?
Explaining everything that applies here would take a while, but to summarize in a few bullet points:
- Be clear. If you're asking a question, imagine that not everyone sits in front of your computer to solve the problem for you. See How to Ask.
- Make it relevant. Answer a question only if you can solve the problem. See How to Answer.
- Use proper formatting and capitalization. Use a spell checker.
- Always cite your sources, and quote passages you didn't write yourself.
