Drupal is highly recognised as one of the best open source web publishing software on the web. It is used on many high profile sites for more information about drupal please visit here
Drupal is open source meaning anyone can take it and use and build their own websites themselves, and out of the box drupal is can do just that, if that works for you great! However most people require a little more than standard installation and highly unlikely but maybe have more enjoyable activities to spend their time on. This is where I come in. I do drupal, everything from basic site and module Installations, to more advanced setups and configurations and ongoing support.
