Blogs MU Template - hiding section intro's and intro header on registration page

Hi guys,

I just installed the Blogs MU (Child) Theme on WP3 Multisite. When I click the "Join our community now.." button on the homepage I get redirected to the registration form. The form looks great, but the visitor has to scroll down a bit because the intro header and section intro's all remain on the page as well (which I feel is quite confusing)

How do I remove those for that particular page?

Thank you!
