Your website is powered by a content management system (CMS), which essentially means that much of the information on the website can be easily changed by you or your group's members. Members may login to the site with their user name and password and create and edit content, adding pictures, discussions, newsletter articles, and many other forms of information etc.
Classic (static) websites required experts not only to set them up but to enter their content using complex-looking hypertext mark-up language (HTML) statements, and such sites were therefore much harder to maintain by members of an organisation or group – often, these websites would quickly become out of date and fail to reflect accurately the work of the group as that work evolved.
The particular content management system documented in this manual is called Drupal and is one of the most flexible and extensible systems among many other similar systems in a new generation of high quality CMSs developed and made freely available by the open source community. Drupal has been designed specifically for supporting rich interaction of on-line community groups.
