Don't ask to ask
Just ask your question directly. It saves everyone time.
Don't do this
User: Can I ask a question?
User: Anyone around, I need help?
User: Guys pls help me?
Do this instead
User: How do I center a div with flexbox?
User: How do I find out which mod is causing a crash? [error log here]
User: Getting "Cannot read property of undefined" on line
42. What am I missing? [code snippet here]
Why?
When you ask permission to ask, you're making people wait for your actual question. Someone who could answer might not be around for your follow up. Just ask directly if someone knows the answer, they'll respond.
