I'm new to drupal, and I have just used the cms to create a little website for a New Zealand seaside community - Port Waikato. Its still a work-in-progress, its mainly used to display my photography of the area.
I must say, i am quite happy with the cms- i've experiemented around with Mambo and a few other systems, but none of them offered the flexibility in design that drupal offers. Kudos to the development team!
I've finally bit the bullet and rebuilt my website with Drupal. I've only been using it since 4.3, you'd think I would have figured it out before now. I was tired of looking for little php doo-hickies to provide some basic functionality. And the agony of adding a new article - gone forever!
This site doesn't even look like its using Drupal, but it is fully tied into the taxonomy system and uses several custom nodes. When admins log in they get a standard drupal interface and can edit every piece of content on the site.
Drupal is damn powerful, and I appreciate it now, but the documentation needs some help. It took a week just to wrap my head around the concepts involved with using it.
