Curricula or Curriculums?

A person who can speak with the dead is a medium. And if you happen to meet two of them, there are two mediums. I prefer curricula for the very simple reason that I studied Latin at school. So I have a soft spot for getting it right. But I'm happy if people say curriculums, but I like the hanker back. Go back to the days when Latin was spoken. My teacher wasn't a centurion.
