When it comes to complexity, Joomla! places somewhere between simple WordPress and comprehensive and advanced Drupal.
The Open Source script is very popular among programmers who create even quite advanced websites with it.
The CMS can be downloaded and viewed at www.joomla.org
Easy to install
Joomla! is quite simple to install. It takes only about ten minutes from downloading to having a working script on a server. It is not as easy as Quick.Cms or WordPress, but is still much simpler than Drupal.
The script has several thousands of free plugins available at the homepage. WordPress may have even more, but to make it as functional as Joomla!, you have to instal dozen or so plugins to start with.
There is abundance of programmer's tools and tutorials available for users. There's also an extensive discussion board.
The script has a comprehensive navigation system, that can successfully manage several hierarchies. It allows to easily manage a site even with couple hundred subpages.
Good looking URLs
Links generated by the script are very friendly and make for better SEO positioning.
When the page design is ready, there will come a time to update the script to a newer version. You can do it from web browser.
Administration panel provides many functions that can be intimidating in the beginning. In time, however, you can master most of them to use the full potential of the script.
Limited adjustment options
Even though Joomla! has many modules and templates, it is always missing something for the more advanced users. It's still better than in case of WordPress.
Server resources and efficiency
Modularity and expendability often means bigger demands on server parameters. This certainly is the case. Still, if the website is not too large and there will not be thousands of visitors, there should be no problems, at least not in the beginning.
Some of plugins and modules for Joomla! are paid, unlike for e.g. WordPress or Drupal. It pays to spend some time to make sure you won't have to buy an addition that is free in some other script.
There may occure some frustrating compatibility issues between some of the plugins. It may turn out that it will be impossible to get some functionalities without some serious work on the PHP code.
Many users, beginners especially, are terrified by multitude of possibilities and functions. So if the website is to be simple and the user or the client is just beginning, it would be wiser to use Quick.Cms or WordPress.
If you have some experience with CMS systems and you're looking for something more than WordPress, but you're still intimidated by Drupal, Joomla! might be just the thing for you. The script is free, has a great number of plugins, modules and templates as well as good technical support. It's a system of choice for multimedia sites and sites with a lot of content - it's when it performs best.
