I've been working on a website 100% from scratch using Node.js for the back-end (with Postgres and Redis), and then React for the front-end. I want to launch the forums in an alpha state within the next couple of weeks, and I need a handful of people to run through a simple process of joining and posting, and then giving me as much feedback as possible.
If you're interested, reply here, and I'll shoot you a PM with a URL and instructions.
