Drupal vB integrates vBulletin forums with Drupal. It allows
existing vBulletin users to log in to Drupal
new vBulletin users to log in to Drupal
existing Drupal users to log in to vBulletin (after initial export)
new Drupal users to log in to vBulletin
a single/shared sign-on when logging in via Drupal
updating user data in vBulletin upon update in Drupal
deleting users in vBulletin upon deletion in Drupal
Unlike vbDrupal (a fork of Drupal), Drupal vB turns Drupal's user-base into the primary user-base (while still allowing existing and new vBulletin users to logon with their user credentials in Drupal) and does not require patches to Drupal core.
Drupal vB currently ships with 3 blocks:
Recent threads/posts
Forum users/posts/pm statistics for the current user
Textimage adds text to image functionality using GD2 and FreeType, enabling users to create crisp images on the fly for use as theme objects, headings or limitless other possibilities.
