 The function call wpmu_validate_blog_signup is passed $blogname,
 $blog_title and $user

 When writing a plugin using the wpmu_validate_blog_signup filter to
 replace the existing check, you cannot handle the condition of the
 blogname being that of an existing user that is not the current logged in
 user.
 e.g. this section of code from the original function:
         if ( username_exists( $blogname ) ) {
                 if ( is_object( $user ) == false || ( is_object($user) &&
 ( $user->user_login != $blogname ) ) )
                         $errors->add( 'blogname', __( 'Sorry, that site is
 reserved!' ) );
         }

 The original functions should perhaps replace the line:
 $result = array('domain' => $mydomain, 'path' => $path, 'blogname' =>
 $blogname, 'blog_title' => $blog_title, 'errors' => $errors);

 with:
 $result = array('domain' => $mydomain, 'path' => $path, 'blogname' =>
 $blogname, 'blog_title' => $blog_title, 'user' => $user, 'errors' =>
 $errors);

 The only problem I see with this is the possibility of some plugin
 referencing the fifth position of $result by numeric index instead of by
 name, which would be a really wrong thing to do.  So I think this
 implementation should not be a problem.
