Login Redirection and User Sync Question

I have installed the facebook authentication button, and nucaptcha.

A few minor issues:

1. When a user signs up, and makes a new blog, signon with nucaptcha is bypassed if they use facebook. Not a major concern, but signon/up with facebok also bypasses your own plugin that asks for a code to create a new blog.

2. Let's say you have a subblog, at http://test.mysite.com and the login for that is thus http://test.mysite.com/wp-admin . Is it possible to redirect them to the main login @ http://mysite.com/wp-admin instead?

The reason I ask about question number 2 is that the facebook login button and the nucaptcha both show up on the main login, but not subblog logins.

I hope this makes sense, if not, please re-read only question #2.

This must be simple, as all I want is the sublogin's to redirect to the main. I run nginx btw. :wink:
