+- 📱 **Mobile Development** - iOS/Android specialists, UX designers
+- 🔗 **Blockchain/Web3** - Smart contract developers, DeFi architects
+
+### Non-Technical Expansion Packs
+
+- 💼 **Business Strategy** - Strategic planners, market analysts, business coaches
+- 💪 **Health & Wellness** - Fitness coaches, nutrition advisors, meditation guides
+- 🎨 **Creative Arts** - Story writers, world builders, character developers
+- 📚 **Education** - Curriculum designers, tutors, learning coaches

+- Consider expansion packs for domain-specific features
+- All contributions must follow our natural language, markdown-based approach
