Shared Accounts Accross Multiple vBulletin Sites

[StephanBotha]

Hi there.

I am currently using phpBB3.0.4 and I'm seriously thinking of switching over to vBulletin if I can get the following answered:

Is it possible to have multiple sites with different vBulletin installations, with different forums and categories share a user table?

What we want to do is combine all our sites so a user only has to register once and then be able to access all the sites with a single user account. When they register, they become part of the default group. The default group has the basic permissions accross all the boards, but the user will have a different avatar, sig etc. Only the username, password and email is shared.

I have managed to get this to work with phpBB3 but the board is a little unstable and has a load of features missing that vBulletin offers.

If there are any bridges or sync'?ng tools available to do this with vBulletin, please le me know.

I thank you for your time
