Web sites created in Drupal are interactive. Users can not only look at your website, but also communicate with it.

Depending on the rights which you provide to users of your website, the users can, e.g., comment on articles and images, vote in polls and top-products lists, send recommendations of interesting contents of your site by e-mail, discuss in forums, write their own blogs, upload images into galleries, and so on.

You can assign different roles with different rights to individual users. Primarily, Drupal distinguishes among three types of roles: web administrator (has all rights automatically), registered user and anonymous user. However, you can create further roles and precisely specify their rights for each function which Drupal offers (e.g., a „club member“ can have access to prepaid services, unlike anonymous and registered users who are not members of the club). Of course, you can also state which content types (and from which users) will appear on the site only after administrator approval.
