Integrating vBulletin into Custom Login

[AussieFreelance]

Hi All,

I am not sure if this is possible or how much work it would involve, but my client has requested that I integrate the vBulletin login onto his existing log in page on his site. This would mean that when someone registers on his site, they are also registering for the forums, and when someone logs in to the site, they are also logging in to the forums. Is this possible to do? I have done it with osCommerce, but I haven't used vBulletin before.

Also, the forums are to only be visible to registered members. Is the only way to do this by setting permissions on the forums, or is there a way to set it regardless of permissions?

Thanks

Patrick
