This page allows you to define an secrecy category. Once defined, the category will appear in the list of available categories on the Define Labels tab and can be used to define a label.
To add a category, click Add and enter a new category name.
To rename a category, select a category and click Rename. Or double-click a category name and rename it.
Once a secrecy category has been defined, it cannot be deleted, but it can be renamed. Every defined category has a bit assigned to it. There are 32 bits available for user assignment.
