An adequate CMS integrated with vBulletin has always been a desire for any webmaster to extend content beyond a vBulletin forum. Even after all the products and plug-ins, there are many content management concepts that are found lacking in a stand-alone vBulletin setup.
vbDrupal offers that bridge between a high-caliber CMS and vBulletin. Drupal is considered by many as one of the best, most robust, secure, extensible content management system out there (deemed best open-source CMS by IBM).

What vbDrupal Offers
With Drupal and vBulletin brought together in vbDrupal, there is full user integration, Drupal blocks in vBulletin forums, and vBulletin thread and PM content in Drupal regions. Also, included is the ability to map vBulletin user groups onto Drupal roles to further integration user permissions and access control from inside of vBulletin. Also, all vBulletin products and plug-ins will continue to function with vbDrupal.
