Overview?????

Action: Edit State• Global configuration

– default permissions for each action and group

• Component options (permissions) – can override the default permissions for a component

• Category – can override the default permissions and component options

– applies to components with categories (Articles, Banners, etc...)

• Object – can override all permissions above for an object

– only applies to articles in Joomla 1.6 core

Many permission screens....• Global configuration




























Idea?!
