add users from one install of forum to another

[Fazzer]

I asked this over at vBulletin but was sent here to ask -

I have two separate forums - Forum A and Forum B

I would like users of forum B upon registration to automatically become members of Forum A which is a seperate install of vBulletin this is the same most recent version on the same server.

Is there a modification available that would let me set this up ?

Its doable but here are the snags.

Unless both boards are set up exactly the same (permissions, default usergroups, etc etc) your going to have to double check everything upon registration, once for board one and once for board two.

Once everything checks out you will have to update both databases (asuming they reside in diff db's) with the user info.

Needless to say it is a very involded hack and how you code it depends greatly on how both boards will be set up, and how you are going to access/update the data in both db's.
