It's something anyone can teach themselves.
The basic sequence is simple:
Set up a Discord. Market it to attract a handful of early adopters. Run a book club using Organizing for Social Change[1] or Beautiful Trouble[2]. Along the way, you build shared language and alignment. People start to get a feel for tactics: collective letter campaigns, pressure targeting, framing, etc.
By the time you wrap the first book, you’ll have a core group with a working vocabulary and some trust. You’ll know how to set up a continuous recruitment and onboarding loop. You’ll be ready for a second round of action. For example, something sharper, louder, more public-facing. From there, it's just iteration after iteration.
The most important seed is a vision holder, someone whose primary job is building solid relationships and gradually offloading the core functions: facilitation, comms, outreach, tech, and education. Don't worry. You don't need money and you don’t need credentials. You need consistency above all, social fluency, emotional and logistical endurance, and a bit of luck.
Trust me when I say it's not easy, but the overhead is basically zero. The only real cost is showing up (again and again and again).
