Managing your Circles
The Central Feature of Google Plus is called Circles. This is where users organise their connections into discreet groups (Circles), e.g. friends, family, work, Customer, Business etc. If you add someone to your Circle they will be notified. However, unlike Facebook, where a confirmed friend request establishes a two-way connection, this is not the case with Circles. People who you've added to your Circle have a choice whether or not they to add you back to their own Circle. You can also allocate your members to more than one group, or set up Circles within Circles, permitting more flexibility and control.
