Drupal 5.8-dev CMS

Drupaul is a CMS (Content Management System) that is very powerful and easy to use. It can save a lot of time with all the core system and third-party modules. A large Web 2.0 website can be built fairly quickly with Drupal. Some of the cons are that it is a large platform and can be slow if not used properly. Any custom PHP, MySQL, third-party modules/themes can easily turn into an issue for the entire system. The environment for developing modules allows easy and deep integration of the system, but can limit your reach. The system is easy to set-up and build a basic website and it allows much more advanced development. It is overall a great free and open-source system!
