Editing or creating category groups
edit category groups in Money. You can
edit Budget groups though.
Category groups are used for internal parts of the program only (such as 'Advisor FYI' or 'Expert Assistant'). If you need to edit them, then you really need to question why, because your ability to use them is restricted. You possibly want a budget group, a standard category or a classification, because you can do a lot more with them.
A list of the category groups as found in the UK 2005 and US 2006 Money versions can be found at the following two links:
If you are wanting to change a category or subcategory, then see Article 317
