quick registration

Hello i'm trying to create my own registration form that will bypass the register.php form. I'm using vbulletin in a lab setting to train principal about technology. I when all the user are registering all at once usernames duplicate throughtout the lab. I can't change my netowrk and all the other fixes that i was told to try never worked. So i have decided to bypass vbulletin registeration form and submit the data in the vbb database directly with no sessions (that is the root of the problem).

could someone help.
