How do I add a moderator to a single space?

Could you say more about how you measured the result? I want to try this but I am not sure what success would look like.

Appreciate the clear steps. The dry-run tip in particular saved me from a mistake I would not have caught otherwise.

Adding a small note: the same idea applies on mobile, just with a bit more attention to tap targets.

This matches my experience exactly. The hard part is staying consistent once the initial novelty wears off.
