Google+ for Google Apps
Finally, + comes to Apps. Thank you, Google. Notable:
For those of you who’ve already started using Google+ with a personal Google Account and would prefer to use your Google Apps account, we’re building a migration tool to help you move over. With this tool, you won’t have to rebuild your circles, and people who’ve already added you to their circles will automatically be connected to your new profile. We expect this migration option to be ready in a few weeks, so if you’d like, you can go ahead and get started with your Apps account today and merge your connections once the tool is available.
