Wordpress Force Post to select category

Question

I am using WordPress to create posts. Is there any plugin or function that will warn me when I don't select a category for the post. It's a headache everytime I post a category, I miss selecting the category sometimes as there is a lot of posts to be made for the category. And after sometime I see those posts in the uncategorized category.

Is there something that will make the category required and force me to select it?

Thanks in advance. Hope I can find a suitable answer.

hah.. its so funny but you can try as below in your functions.php file

function force_post_categ_init() 
{
  wp_enqueue_script('jquery');
}
function force_post_categ() 
{
  echo "<script type='text/javascript'>\n";
  echo "
  jQuery('#publish').click(function() 
  {
    var cats = jQuery('[id^=\"taxonomy\"]')
      .find('.selectit')
      .find('input');
    category_selected=false;
    for (counter=0; counter<cats.length; counter++) 
    {
        if (cats.get(counter).checked==true) 
        {
            category_selected=true;
            break;
        }
    }
    if(category_selected==false) 
    {
      alert('You have not selected any category for the post. Please select post category.');
      setTimeout(\"jQuery('#ajax-loading').css('visibility', 'hidden');\", 100);
      jQuery('[id^=\"taxonomy\"]').find('.tabs-panel').css('background', '#F96');
      setTimeout(\"jQuery('#publish').removeClass('button-primary-disabled');\", 100);
      return false;
    }
  });
  ";
   echo "</script>\n";
}
add_action('admin_init', 'force_post_categ_init');
add_action('edit_form_advanced', 'force_post_categ');

NOte:- javascript must be enable to run this
