No Registration form and no SiteAdmin section in

Using BP Business Theme with WP 3.0 and BP 1.2.4.1 (no WPmu) and I have no registration form and no section in the Admin entitled "Site Admin"like it says I should have here: https://premium.wpmudev.org/the-buddypress-manual/letting-people-register/

http://www.my-site.com/wp-login.php?action=register just goes back to the home page.

The demo theme here doesn't show any registration for either.
