WordPress integration with vBulliten

Here is the text of 2 posts on the vBulliten forum regarding integrating login with a vBulliten Forum & a WordPress blog. I’m still a newbee & have tried ro get some insight into how to code this a few times. Does anyone have a way to explain this. Thanks.

“I’m developing a web application that I want to have an accompanying message board. Is it possible to integrate my user accounts for my web application with vbulletin’s user accounts? Specifically I want to be able to do two things:
1. Not require the user to create separate user accounts — their account for my website will create the vBulletin account.
2. Not require the user to login separately to vBulletin — if they login to my website, they should get logged into the vBulletin forum.
I want to do this for a few reasons, but the main one is to encourage forum participation by making it easier for users of the website to jump right into the forums if they wish. I couldn’t find any clear answers about how easy this is to do with vBulletin? Is this functionality built in, or can it easily be added?

Thanks for any information you can provide on this.”

“As long as you have competent knowledge of PHP, this shouldn’t be a hard task to do. vBulletin provides a data managers to add/modify/remove data (e.g. users, posts, etc.). Also, the login process is also relatively simple (a few cookies).”
