I had the idea to make this thread while looking through the Clubs & Crews forum. Since the search bar oftentimes doesn't turn up what you want, I decided to make this as a reference point for what Clubs & Crews already exist. This is organized by category, rather than my previous list organized alphabetically.
If I missed your club/crew, then post here with the name of your club/crew and a link to it. I believe I have almost every single active club, though.
Thanks, and enjoy!
