Referring to /wp-admin/users.php
Suppose you create *a second blog* of which you of course are a member and admin.
Now you add a user to this blog (via the enter user email).
How do you then remove that user?
If I try that I get "This function is disabled".
I'm not trying to remove the user from the site itself, but there should be a way for a blog admin to remove a user from their 'own' blog.
