The Minimum titles defines who can create a particular entry in Guardian Tracking.  The minimum title selected, or any up line title, can create the entry.  It has nothing to do with who you can create the entry about or who can view an entry once it is published.

In the example below the category "Absenteeism" was set to "minimum title".  With that setting anyone with create rights could create documentation under that specific category.  We changed the setting to "Supervisor" and now only a person with the title of "supervisor" or above will be able to create documentation under the category.  Notice that the category of "Award Nomination"has "Civilian Staff" set as the minimum title.  In this example "Civilian Staff" is in the last position on the title list.  This means that everyone in the organization can create documentation under the "Award Nomination" category.
