I’d replace “be prepared to explain to others” etc with
“Please ensure it is clear in your post how it relates to selfhosting”
Be prepared is a bit vague. Your preceding explanation calls out that what is in the poster’s mind is often not clear to others, and the rules are there to remind people of the standards required. My suggestion is still a little vague, but I suspect anything blunter might cause offence.






Yeah the updated/edited version works for me, nice one.
