I am going to add vBulletin Forum and Blog to an existing site (e.g. [url removed, login to view]). I need to integrate the current website user login with vBulletin user login so that users can sign in to the main site but will be able to use vBulletin Forum and Blog as well. This is vBulletin 4.0.3 licensed version. Please bid only if you have done this work before. This script should not affect any of the existing features of the site.
