Post a Demo and Make People Comment to Opt In

Post a Demo and Make People Comment to Opt In is a communities tactic for getting your first users: To gather feedback in groups that ban links and self-promo, post a short demo and have interested members comment, then deliver access by DM instead of dropping a link.

It's a strong fit for Info products / courses teams, and works especially well for Facebook/Slack/Discord communities with strict no-promo rules. As a communities play, plan for medium effort and expect results to show up quickly, all grounded in 1 linked primary source.
