Google Video Chats are a great way to collaborate with someone or someones who are not at the same place as you.  You can easily start up a video chat, share your desktop or browser window and connect with people around the world using your Google Account.  These are private chats and are so easy and quick to setup that you will save a lot of time and effort in trying to work or communicate with someone.  I have used this many times to talk with others and have those conversations that email or text chatting just do not allow for.  It is easy to get started and easy to use, watch the video below for a quick tutorial to get started.
