The pilot is live with working signup and intake forms backed by a real database. I am looking for honest usability feedback: try signing up as a builder or a practitioner, complete the intake form, and report what was clear, confusing, or missing. About 15 minutes, start here: <a href="https://brainpick-kohl.vercel.app/usability.html" rel="noopener noreferrer">https://brainpick-kohl.vercel.app/usability.html</a> This is a volunteer beta, no payment involved. The stack is a static front end with serverless intake endpoints, and the repo runs Playwright end-to-end tests against production in GitHub Actions daily. Feedback of any kind is welcome, including here in the comments.</p> showdev buildinpublic testing webdev
