[Plugin: WP to Twitter] Possible bug in wp to twitter

I found a possible problem in the function jd_twit_future(), although I am not sure if it forms a problem.

function jd_twit_future( $post_ID ) {
    $post_ID = $post_ID->ID;
    if ( $jd_tweet_this != "no" ) {
		$jd_post_info = jd_post_info( $post_ID );
		$sentence = '';

As you can see, the if statement checks for a variable that is not there. The if therefore always is true. It would be best to add the line

$jd_tweet_this = get_post_meta( $post_ID, '_jd_tweet_this', TRUE);

before the if.
