Redirect after registering on WP?

This discussion is related to the Vanilla Proxyconnect addon.

How can I make it so that after a user registers via the WP registration page they end up on their forum profile? The ProxyConnect plugin doesn't create an account on the forum until they visit it for the first time.

This can avoid the problem with it creating a forum account with the WP user's display name if they changed it before visiting the forum. It can also avoid confusion with the profile settings. I just don't know how to make do this.

EDIT: Nevermind, I found this plugin: http://wordpress.org/extend/plugins/peters-login-redirect/
