Building Websites with Joomla! 1.5

Joomla [sorry, I just won't add that exclamation mark after it] is targeting the novice website designer and programmer. By some definitions, a designer need not be concerned with the messy details of actually making webpages. However, Joomla is easy enough to pick up that a designer might well be tempted to indulge in actual page design and generation.
It does aim at websites where the intent is for users to have a persistent login. To this ends, Joomla offers a separation of functions, for the user and for the administrator [you presumably]. As the book demonstrates, it's pretty easy for you to create user accounts. The specialisation for content management is shown when there is the concept of groups of users. Joomla offers Registered, Author, Editor and Publisher. With subsidiary groups of Manager, Administrator and Super Admin. The administrative tasks are done within a simple GUI that frees you from memorising arcane command lines.
Joomla also has an interesting functionality. It lets you, the website author or owner, publish Joomla-generated URLs that are search engine friendly. Various search engines tend not to store long URLs, where there are many arguments in these, after the host name. The assumption is that the URLs refer to dynamic [ie. transient] content. Hence there is little point to the engine storing these URLs, or the pages pointed to by them. But you want the engine to store your website's URLs, right? What Joomla does is rewrite the URLs in a more compact form, which improves the chances of an engine recording these. And thus offering your website in its free results.
