Hello, We are running a semi-large vbulletin forum on 3.6.x version We have recently designed a drupal CMS for our website, we want to integrate members from vbulletin with drupal. Requirements: 1. Using amember can we integrate vbulletin and drupal ? 2. We want all our existing users of vbulletin to be able to login to drupal as well. 3. One single registration system for both vbulletin and drupal. 4. We will consider adding shopping cart module to our drupal + vbulletin in recent future. 5. We will also have paid subscription features on our website. If amember can do the same, we will go ahead and purchase immediately. Thank You.,
