How do I see which features are on for my account?

On the Welcome page, select Activity to see the Switchboard and Analytics. The Switchboard lists your account features with their live state: Podspun.com, Websites, the Data API, News / Blog, the Store, Donations, Email Campaigns, Payment Setup, and your Contacts count. Each row has a Configure link straight to that area’s setup, so turning something on or adjusting it is one click from Activity.
