To add customers to groups

• Click on the Customers tab.
• Then in the lower left, click on the Group icon.
• On the left side of the window will be two columns.  The most left column is the names of your groups.
  The other column is the names of your customers.
• All you need to do to add customers to groups is to click and drag the customer into the desired group.
• Looking at the group, there will be a number next to the group name to show how many customers are in that group.
