MultiHub Forum

I'm helping to revitalize a local neighborhood association's online forum, which has become inactive and occasionally hostile. We need to draft a new set of community guidelines from scratch to encourage positive engagement and clear up confusion about what's allowed. What are the essential elements to include beyond the basic "be respectful" rule? How do you effectively address issues like promoting local businesses, discussing contentious local politics, or handling misinformation without stifling genuine conversation? We want the guidelines to feel welcoming, not like a strict rulebook.
