Tout d'abord, rendez-vous dans votre template overall_header et rajoutez après la balise CSS au début du template :

Code:

<link href="//solrainha.github.io/honeybee/honeybee.css" rel="stylesheet"/>

Remplacez l'intégralité de votre template viewtopic_body par le HTML :

Code:

<script type="text/javascript">

• Ce code ne prévoit pas d'afficher les éléments clasiques de profil, il vous faudra donc tout désactiver pour les messages dans votre panneau de configuration.
• Vous pouvez ne laisser qu'une icône (visible sur le schéma) que vos membres pourront donc modifier quand ils le souhaient par leur propre profil.
• La largeur forum doit faire 950px minimum.
