Google+ rollout tips
We recommend you follow these steps to roll out Google+ to your users:
It's important to understand how Google+ works, what your users can do, and what they can share outside your organization before you enable the service.
Make sure users' computers meet the browser, operating system, and other requirements for Hangouts.
You might need to adjust your firewall settings for Hangouts to work.
You can enable the service for your entire organization or just specific users. Consider enabling Google+ for a small group of users first as a trial, and then enable the service for the rest of your organization.
Activate Google+ premium features to restrict user content to your organization only by default, restrict hangouts to only those who are invited, control whether users can use Hangouts On Air, and more.
Make sure you let your users know that Google+ is available for their Google Apps accounts and how they can sign up.
