Forum Integration with existing website users database
 

Hi,

I would like to find out what are the options to integrate vBulletin 4 with my website existing users database.

I have recently installed vBulletin 4 successfully on my website. My website consists of more than 10,000 registered users.

May I know how do we ensure that these existing users are able to use the forum without registering again?

Please advise. Thank you.
