Alcoholics Amonymous is a well known anonymous organization.
It continues to thrive, and all the members are anonymous.

Edit: found my answer on another thread.

Wow, funnily enough its been nearly 5 months now since Anonymous Posting was enabled, and I'm *still* having all the same issues with it as I did back then.

Why isn't this being sorted? Why aren't members issues being addressed? Do you no longer care about your actual membership base?
