In my move over to lemmy I got nostalgic for how some older things were done, what you might be talking about are FAQs for specific topics like we had in the Usenet days. If this interests you, I have a new community started for collecting and creating those kinds of things. Not much there yet but I’ll grow it over time and would love for others to contribute.

And a shameless plug for my other community https://lemmy.dbzer0.com/c/bbses
If you want a community with training wheels and is open to general discussions, come say hi. Its a place where you can work past the fear of being downvoted or insulted. You are welcome here. 😀
