[Plugin: WP phpBB Bridge] user issue

Hi

My main wordpress site is behind a paywall. So when this is installed and someone clicks to register, it takes them to the forum to register. Is there any way this can be changed? Id like people to be able to register on wordpress as usual or register on the forum and have access to both wordpress and forum with the same login details.

Thanks
