How to share user data between 2 vbulletins?

[zjs2k]

Hello, everyone,

I plan to purchase another license of vBulletin and setup a second forum under the same domain. I would like to have visitors to register only once for both forums. It is ok if they need to login twice, but I want to limit the login process to just one. I prefer to have the users to manage the profiles seperately.

I want to disable the registration of forum2 and force users to register at forum1 only. And when logging in forum2 for the first time, the script should verify user data from forum1. Then copy the user record from forum1 to forum2. From now on, the users should be able to update his/her profile, etc. This is just my idea of doing it. If you have a better idea, please do let me know.

Is this hack possible? I tried to search the forum and I don't even know what to search. The most posts I found were about multiple domains. I want to make sure the feature is possible before I buy a second license.

Any help will be very appreciated.
