Google+ Hangouts: Account Setup after May 2013
Planning to use Google+ Hangouts to connect with prospects, clients, friends, and family soon, I searched for an expert to help me get started. After viewing a lot of YouTube videos for insight, I decided Ronnie Bincer, The Hangout Helper, with the best resource to follow. This 12:39 video is part one of his account set up series. I found Ronnie as a result of searching for answers on how to move my YouTube user account which is connected to one Google+ account to another Google+ account that I want to use for Hangouts.
