In Chatter Answers and Ideas, use zones to organize ideas and answers into groups. Each
zone can have its own focus, with unique ideas and answers topics to match that focus.
Before Summer ‘13, Chatter Answers and Ideas used the term “communities.” In the Summer ‘13
release, these communities were renamed “zones” to prevent confusion with Salesforce Communities.
To work with zones in Apex, use the Answers, Ideas, and ConnectApi.Zones.
