title: How can I change the text on "post comment" button?
body: <p>I am building a site for some therapists using wordpress and am using the comment section of a post for a question and answer with the therapists. However I cannot find where the text is coming from on the "post comment" button. I would like to change it to "Post a Question".</p>
  
  <p>The comments.php in the theme has nothing about it and I cannot find it anywhere in the main wp-comments-post.php </p>
  
  <p>Any help would be great!</p>
  
  <p>Thanks</p>

  <p>Edit: My confusion has been that I cannot find the 'post comment' anywhere. Also if I just add it then there becomes two buttons and the new one does not actually submit. Here is the code.</p>
  
  <pre><code>&lt;?php
  /**

   * @file           comments.php
   * @package        Pilot Fish
   * @filesource     wp-content/themes/pilot-fish/comments.php
   * @since          Pilot Fish 0.1
