I've been building up a membership system for my website for the last couple months. It's finally out and announced to for everyone to find. I have to give a big thanks to @brethudson for a big chunk of the web programming that went into this.
The system is announced in this video: https://www.youtube.com/watch?v=BJncE8ZVIiE
