title: Limit the number of words of a post shown on the home page of a wordpress blog
body: <p>currently my wordpress theme shows all the words in a post on the homepage, even of very long posts. I would like to limit that to a reasonable number lets say 1500 words max to be shown on the home page, then there should be a "read more" link underneath.
  Im using the toolbox theme heres the 1. content.php and 2 index.php.</p>
