I realized I didn't have a post on this here.
The ACO ML was created when ACO was, to handle discussions about ACO features off the Anime Cards Mailing List. I prefer to discuss new features there, all things considered, so that bad ideas can die an early, and un-googled, death.
I look forward to hearing your opinions! There is a new block on the right, click away to sign up.
