title: bbpress code to display total number of topics
body: <p>I am using wordpress to design a website and I integrated bbpress plugin. I will like to display the total number of created topics at the frontend, but I can't find how to do this. I tried using </p>
  
  <pre><code>bbp_get_forum_topic_count();
  </code></pre>
  
  <p>but it displays total number of topics in a selected forum. I don't want this, I want to display the total number of all the topics created on the site.
  Any help will me much appreciated. Thanks</p>
