Drupal, not difficult as you thought
Ever since i started knowing and then learning about the world of cms (content management system) it has been almost four years. Yeah for me is a long run but for you maybe not.
I started testing some cms at the time being as you may now utterly know (joomla, wordpress, typocms and of course drupal) there were some other stuff too but i can`t remember them all. Over all I could see the power drupal had to offer with its cck (content construction kit)and views I could also divide content to category or as drupalers* call it taxonomy.
