I finished installing WP 3.3. After adding the lines from "network setup" to wp-config and htaccess I do not see network admin (screen shot attached).
However, I can enter mysite.com/wp-admin/network/ and see super admin and everything I would expect to see. Now this may be only partially true because I have never istalled multisite before, but it seems to be what I want.
In other words, the basic setup seems to be in place but it does not show up when I enter mysite.com and log in. I see the standard WP page "Welcome to your new WordPress site!". The only way I can get to the network admin page is by entering mysite.com/wp-admin/network/.
