The purpose of communities is to share information and support collaboration between companies, their customers, and their partners. A Salesforce organization can have multiple communities, each serving a distinct purpose or segment of customers/partners.
To enable communities in Salesforce, log in to your Salesforce Developer edition and complete the following steps:
- Go to Setup | Customize | Communities | Settings.
- Select Enable Communities
- Enter a domain name prefix that will uniquely identify your communities on Force.com, and click on the Check Availability button. If the domain prefix is already used, enter a different domain prefix and try again.
