In your examples use have Member Types of;
Member,
Mailing List,
Visitor,
Regular Attender, etc.
I believe that your design intent is for Member Types to be an organizational tool for communication.
Would it be advisable to create such Types as;
Pastors ( we have 7),
Staff ( we have 40+),
Interns, etc.
in order to use these as communication categories?
I am really asking for some coaching as to what you would recommend.
