Running additional scripts during registration

[ferdia]

Hello all. I'm currently building a site for a client and we have decided to use vBulletins user manager for the site at large. I have figured out how to do that, but I need to populate some other tables that the site at large will use during the registration (basically to allow users to access other features as soon as they register).

Where would be the best place to place a set of mysql INSERT commands in the registration script, baring in mind I will need vBul's username variable to associate the tables properly.

Thanks in advance,
Ferdia
