MRBS is a free, GPL, web application using PHP and MySQL/pgsql for booking meeting rooms or other resources.
This very simple module offers single sign-on integration with MRBS and Drupal. The module uses Drupal user accounts, permissions and sessions with MRBS. Currently the module has only been tested when MRBS is installed in a subdirectory of Drupal root directory, but it should be quite easy to modify it for other installations.
Do you want a more interestingly themed system message from Drupal? Enjoy Growl messages on OS X? Then this module is for you.
This small module uses a simple override made available in Drupal through hook_theme_registry_alter() to output the system messages through jquery based popup messages. The messages fade in and out in a suitably sexy manner and will queue up underneath one another if necessary.
