PhotoPost and PhotoClassifieds on seperate domains with common user base?

[drawoh]

I am running the latest Version: 3.0.7 of vbulletin and I want to buy your PhotoPost, Classifieds and Review programs. I want to know if I can have a unified membership base if I use different domains for the classifieds, reviews and photopost that are on a domain different than the vbulletin board that I want to intergrate them into. They will all be on the same server.


Example:
vbulletin forum with the domain -www.xxxxxforums.com* xxx denotes a name
Photo script with the domain -www.xxxxxphotos.com* xxx denotes a name

Classifieds script with the domain -www.xxxxxclassifieds.com* xxx denotes a name

Reviews script with the domain -www.xxxxxreviews.com* xxx denotes a name

Can they all have the same unified membership base. What I want is that when a member registers at one of these 4 sites they are registered at all 4sites.

Need an answer by tomorrow so I know what script to buy.

If they are on the same server then they can share the members database but you will not have automatic log-in when going from one domain to the other. Cookies can only be shared on the same domain and since each would be on different domains then the member would need to log-in to each site.
