Not a duplicate here, there's an array for guests and an array for registered users

                    'user_colour'        => $row['user_colour'], 

#
#-----[ BEFORE, ADD ]------------------------------------------
#

                    'group_id'            => $row['group_id'],     

#
#-----[ FIND ]------------------------------------------
#

    for ($i = 0, $end = sizeof($post_list); $i < $end; ++$i)

Make sure we don't display hidden groups

    // Get groups name on the board
    $sql = 'SELECT group_id, group_name, group_type
       FROM ' . GROUPS_TABLE . '
       WHERE group_type <> ' . GROUP_HIDDEN;
    $result = $db->sql_query($sql);
    while ($row = $db->sql_fetchrow($result))
    {
       $groups_name[$row['group_id']] = ($row['group_type'] == GROUP_SPECIAL) ? $user->lang['G_' . $row['group_name']] : $row['group_name'];
    }
    $db->sql_freeresult($result);
