BuddyPress.org

I’m trying to remove the section of the registration page that allows new users to create a blog during registration. I know you can remove the option through the admin network settings, but I still want users to have the option to create a blog after registration.

The website uses WordPress Multisite and BuddyPress along with a “Secure Invite” plugin that requires new users to be invited by existing users. If I understand correctly, the BuddyPress Registration page is responsible for serving up the registration options from other components of the site, which currently include,

WordPress (Username and Password)
*Multi Site (New Blog Registration “Blog Details”)
BuddyPress (Username + Profile Field)

Is there a way using a child theme to have the BuddyPress’s registration page hide the Multisite Registration options (i.e. “Blog Details”) or just not serve them up?

Here’s a screen shot of the options I’m looking to remove, Screen Shot
The site address is, http://backpackersjournal.com/

I’m completely stumped by this one so any help would be amazing!

WordPress 3.8.1, BuddyPress 1.9.2

Thanks in advance!
