What is Google+? Google+ is a soical networking tool, much like Facebook. For our domain, that would not be the intended use. What it offers for you and for others, is the ability to create what is called a hangout. A hangout will use your microphone and web camera (if you have one) and will allow you to have a virtual meeting.
So, instead of traveling many miles to confer with others inside ESU 4, you can use this as a resource for video and audio. More importantly, you can also share your screen.
If you would like for me to help you out with this, let me know. I can invite you to a hangout and show you how it works.
In order to get started, you would have to create a profile. If you go to http://plus.google.com, it will walk you through the steps. After you are done creating your profile and have finished setting up your account, then you will see a +You button when you login to the ESU 4 domain. Please note, that this account is still managed by ESU 4. And, if you want to connect with others, they must also have Google+ enabled.
