Hi all. For Joomla / phpBB there is an non-invasive bridge available supporting all authentication backends that Joomla provides: http://rocketwerx.com/products/rokbridge/overview This is quite nice as all other solutions require code modifications which may lead to upgrade problems. The latest Bridge available for Drupal is for v5.7: http://drupal.i1media.no/ phpBB in general is my favorite forum software as is scales very well and is easy to handle. Theming phpBB is a bit harder than e.g. fluxBB but still possible. Best Regards Marcus
