Up to Joomla! Although this didn't pose problems for most sites, it was nevertheless a strange restriction. That's why Joomla! Categories can now hold an unlimited number of subcategories. This means that you can have a hierarchy like this:. A category can hold as many subcategories as you need. This concept is called "unlimited nested categories".
In most cases you won't need more than two or three subcategories, but if you do, there's nothing to stop you.
You can check the content category hierarchy in the Category Manager. Child categories are displayed indented, with small gray lines indicating the sublevel:. The above screenshot shows the nested categories contained in the sample data that comes with Joomla! As you can see, all article content is stored in subcategories of the main category Sample Data-Articles.

Site members may have exclusive group access to special content and members of the editorial team may be allowed to access the backend and perform site management actions such as creating or editing articles.
You can create as many user groups as you like and control the rights of users in detail. In short, you can add users, assign them to custom groups, and define what these user groups are allowed to see and do both on the frontend and backend of the site. You can set permissions on different levels: on a site-wide level, on the level of components, right down to the level of individual articles or modules.
The site-wide permissions are set in the Global Configuration Permissions screen:. The new ACL system may be very powerful, but it can also be quite complex. You need to carefully plan how you want to set it up. But it can be fun too—it's really cool to be able to specifically control which pages different registered site user groups can see or edit.
You'll see examples of this later on in this book. Of course, you don't have to use ACL when running a Joomla! If you're fine with the basic levels of user access that were present in 1. The 1. In Chapter 5 , you'll learn more about managing site users with the new Access Control Levels system.

This feature can be quite useful for people visiting your site through outdated links, as they won't just hit a dead-end error page any more. Moreover, search engine spiders can now keep track of valuable content, even after it has been moved to a new location. In this quick tour, we've only just touched upon some major changes in Joomla!
