What is the difference between a Project and a Category? For example, the profile for Thomas Cushman Sr., has a category for Mayflower Families, and a Project of PGM. Shouldn't all Mayflower Families (by Category) also be part of the Mayflower Project?
In the case of a person who looks like he should be added to the Mayflower Project, should I also add Mayflower Familes as a Category? (see Cushman-137 for example)
These are only two examples. I am trying to apply the right projects and/or categories to the profiles I manage, or are in my direct line, and came up with this question.
This seems confusing...Is there something I can look at that explains the usage of categories vis-a-vis projects?
