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.
Note
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.
