Asking questions correctly/en

Do Some Research
Review the help center. Have a look at FAQ. Check what has been asked at community noticeboard. If you think that "do this" button can solve the problem, try that first. There's no point asking a question that can be answered with simple search or documentation read.

If you won't work on fixing your problem, why should we?

Don't ask to ask
There's more than two websites dedicated to tell you about this: Don't ask to ask, just ask, Please Don't Say Just Hello In Chat.

But in nutshell: if you want to ask something, you don't need to say "I have a question", or "Can I ask you something?". Just ask your question right away. Like, "How do I enable this extension?" or "I can't upload  file, how do I upload it?" From there, we can just work on fixing your problem, or answer your question. If you say "I have a question", we need to ask you back, "What is the question?", and therefore you are wasting bit of your time because we have to wait for your actual question to answer it.

Be Patient
As k6ka wrote on Discord...

1. Patience is a virtue in life. 2. This is a volunteer project, so people are not sitting around staring at Discord 24 hours a day ready to respond in a heartbeat. They have lives of their own and things of their own to do as well. 3. If someone doesn't respond immediately, sending them more messages won't make them respond any faster. If I'm away on vacation, sending me fifty emails will not get me to respond any faster than if you just sent me one email. In fact, sending me more messages might delay your response since now I have to weave through your ocean of messages.
