I have a site with the directory part being run by Links, and the user registration/forums run by vBulletin. Both scripts are using separate databases.

I have had a search around but haven't found much information on how to connect to another database from Links. What I would like to have is some kind of plugin or global that can connect to the forum database and extract the information I want (e.g. recent thread titles, number of unread private messages).

If someone can point me in the right direction that would be a good start .
