So you're looking to create a web site and are wondering if Wordpress is the right CMS tool for you. Good news is that the Wordpress community and volunteers have come up with some ideas on how you can lear if Wordpress is right for you. You can learn about this by going to http://wordpress.org/extend/ideas/

You can also see what kind of sites are built with Wordpress by going to their showcase: http://wordpress.org/showcase/

For beginners, it is recommended that you review the documentation that is available for you at the Wordpress site, see: http://codex.wordpress.org/Getting_Started_with_WordPress#WordPress_for_Beginners

You can also read a 3rd party evaluation of Joomla, Drupal and Wordpress which suggests that Joomla is the most favorable of the 3 most popular open source software programs for building web sites. You can find this study at:
