Are there any AI alignment community sites that focus on introductory safety discussions and newcomer questions?

Yes. A few community sites are especially friendly to introductory AI safety / alignment discussion and newcomer questions:

• AI Safety Support — a newcomer-focused community with mentoring, intro resources, and space to ask basic questions.
• LessWrong — not exclusively for beginners, but it has a lot of introductory AI safety content and is welcoming to well-posed newcomer questions.
• Alignment Forum — more research-oriented than beginner-oriented, but still good for reading foundational discussions and asking informed questions.
• EA Forum — broader effective altruism discussions, including many accessible AI safety posts and beginner Q&A.
• AI Alignment Forum / community Discords and Slacks — various local or project-specific communities often have beginner channels.

If you want, I can also give you:

1. the best site for pure beginners,
2. the most active community, or
3. a short list of beginner-friendly AI safety forums and Discords.
