CMS examples

I have been checking several sites from schools which have been created with different CMS, such as Drupal, WordPress, Joomla, PHP-Nuke, SPIP, Zikula (mostly in Catalonia), Mestre a casa (offered by Conselleria of Valencia) or Moodle.
All of them seems to me quite interesting, and I am sure all provide to creators lots of possiblilties to make alluring websites.That's the main thing in my opinion. In first instance,web pages should catch the atention of visitors with amazing photos, colors, drawings, etc. It is also important to show at first sight a general idea of the information that the site can offer you and it should be very aesy and intuitive to find the information you are looking for.
By that reasons I would like you take a look the websites of Navarro Santa Fe and Doctor Balmis.Here you can find sites using wordPress and Joomla respectively, but the CMS you use is not as important as the contents and the appearance. For instance, in Doctor Balmis' site the last news are from five days ago, and this is an important issue if you want to keep the interest of visitors..
