My choice of Content Management System is Drupal. Drupal does not provide such a complete default install as other CMSs, however, all you need to do is install a couple of modules and you get the same effect. Drupal is probably not quite as quick to pick up as other CMSs but this is only because it is much more powerful and once you are familiar with it, you will realise how amazing it is!

You'll find there are 4 distinct areas to Drupal:

1. Creating and organising content
2. Installing modules
3. General setting up of modules and functional areas of the site
4. Administering site settings
