Using PM 4.1.3 for mac This is from the manual:
"A folder is a storage for recipients, groups and sub folders. A group is a list of references to some recipients. Thus, a recipient can exist in only one folder (or at the root level) but can be referenced in multiple groups. For example, you can create a folder "customers" and a folder "prospects", and create a group "newsletter" that references contacts from both folders." How do I create the reference when I've created a group or folder? Stan Lord
