Change usergroup for newly registered users

[scritty]

Currently when someone registers with our site they are given 10MB of disk space for uploading their photos and are classified as a Registered user. I want to run a temporary promotion that will give new users who register with our site 30MB of disk space.

I've set up a new usergroup called Promo. What I need to know is where in the code can I change it so that a new user is automatically registered as a Promo user instead of a Registered user. Then, when my promotion ends, I can revert back to making new users part of the Registered usergroup.

Are you using a standalone install integrating with a forum? The answer can be different depending on your answer.

As far as our code you can edit register.php and change the coding to not drop them into usergroup 4 which is registered users but the new usergroup numeric number.
