As the content would not be time sensitive and doesn't go out of date I was advised to use something such as Mambo. I know Drupal better, although I just started using it, so I wonder whether you guys think it would be fine to use for the above purpose. Also, I would ask what sort of content format should I use; page, forum, blog or story? And what about the URL, enabling clean URLs doesn't seem to help too much. Thanks!
