jQuery(document).ready( function($) {
    
    $('#comment').keyup( function( event ) {

        if (event.keyCode == '13') {
            content = $(this).val();
            content = content.replace("\n\n", "\n");

            if ( total >= 2 ) {
	            alert("That's " + total + ' paragraphs. Maybe you should consider a writing blog post response instead.');
