First topic message reminder :

In other forums, I've seen it possible to display only one author's message in a topic post. Are there any mod that can do that?

no，like this

So hide all comments less the author. Create a new JavaScript page with investment in the topics (go to Adminstration Panel > Modules > HTML & JAVASCRIPT > Javascript codes management) with the following code:

Code:

(function ($) {
  'use strict';
 
  $(function () {
   
  var $author = $('.post').first().find('.postprofile-name').text();
   
    $('.post:not(:first)').each(function () {
      var $this = $(this);
     
      var $pauthor = $this.find('.postprofile-name').text();
     
      if(new RegExp($author, 'i').test($pauthor)) return;
     
        $this.fadeOut();
     
      });
    });
})(jQuery);

Sin_Ger since you are using pedxz's code can't mark this as solved?

thank you @Pedxz for your help
