A quick summary of advice received: (thanks to those who responded!!) Various content management systems were suggested, such as Plone http://plone.org/ Drupal www.drupal.org Other CMS packages are reviewed here: http://www.opensourcecms.com/ http://www.cmsmatrix.org/ However these were all rather over the top for what I needed: a simple User-Management script that could be tacked on to some pages. Two resources surfaced: http://evolt.org/node/60384 http://www.phpfreaks.com/tutorials/78/0.php and I will be checking them out shortly. Tim in Ireland.
