New shortcode for the hidding error message

Hi, great plugin.

I come across with problem where I use shortcode user_verification_check on the custom login page. I need to visitor after verification have login form.

Problem was that I constantly get error message on that login page when visitor is not under verification. For that reason I create new shortcode in my theme to fix this problem:

if ( !shortcode_exists( 'user_verification_check_validate' ) ):
	add_shortcode('user_verification_check_validate', 'uv_filter_check_activation_validate');
	if(!function_exists('uv_filter_check_activation_validate')) :
		function uv_filter_check_activation_validate($attr, $content = NULL) {
			if( isset( $_GET['activation_key'] ) || (isset( $_GET['uv_action']) && isset($_GET['id'])) ) return do_shortcode($content);
		}
	endif;
endif;

Is it possible for you to made something like this or to add some attribute to your shortcode to we can hide error messages for the standard visitors?

Thanks!
