Where can I find a "Where can I find a community" community?

I'm assuming that there are communities on Lemmy about the design of moderation and user reputation systems, but I'm not sure where to look. So I'd like to ask in a community dedicated to asking where to find a community for a topic, but I don't know where that is either. So I'm asking in this community where there might be a community where I can ask where there might be some community for some other topic. ^..;;

Uh, any recommendations for where to direct that kind of question?
