I signed up for a one month subscription to D&DI, to try it out. Now I actually want to sign up for a year, and I can't figure out how. I missed my first opportunity, as a I saw today that my subscription was automatically renewed for a month. That was annoying, but really nobody's fault but mine. But now I'm looking all over my account profile and D&DI management page, and I can't find anything about switching to a one year renewal, or indeed even switching automatic renewal off. How do I do it?
