The rules
-
Ask about one thing at a time
A thread with a single, specific problem gets answered. A thread with four gets skimmed. Split them.
-
Show what you already tried
Versions, exact error text, the command or setting you changed. It is the difference between a guess and an answer.
-
Pick the right mode
Question when you need a working answer — those can be marked solved. Discussion when you want experience and opinions.
-
No promotion
Do not post to market a product, yours or anyone else's. Linking to something you built is fine when it genuinely answers the question and you say it is yours.
-
Be civil about disagreement
Argue with the answer, not the person. Condescension, name-calling and pile-ons get removed regardless of who is technically right.
-
Keep other people's data out of it
Redact hostnames, keys, tokens, licence numbers and anything that identifies a colleague or a customer before you paste a log.
-
Report rather than reply
If a post breaks these rules, use Report. A reply telling someone off leaves the problem on the page twice.
What moderation does
New accounts may have their first posts reviewed before they appear. Posts that are reported by enough members are hidden pending review. When something is removed, the reason is recorded, and the author is told which rule it fell under.
Practical questions about accounts, notifications and thread states are answered in the forum FAQ .
