ok, put the css in your style.css.

then maybe try this code in your functions.php file

add_action( ‘bbp_theme_after_reply_author_details’, ‘mentionname_to_bbpress’ );
function mentionname_to_bbpress () {
 $user = get_userdata( bbp_get_reply_author_id() );
 if ( !empty( $user->user_nicename ) ) {
 $user_nicename = $user->user_nicename;
echo '<ul><li><font class=bbp-user-nicename>' ; 
echo “@”.$user_nicename.’</font></li></ul>’ ;
 }
 }
