bueno tengo una duda con este plugin, en la instalacion hay un paso en el que me dice que debo modificar unas lineas de el archivo 'ADMINCP/USERGRUPS.php' pero no encuentro por ningun lado ese archivo, alguien tiene idea? :

3. OPEN ADMIN/USERGROUPS.PHP AND FIND:
		"cancustomtitle" => $db->escape_string($mybb->input['cancustomtitle'])

REPLACE WITH:
		"cancustomtitle" => $db->escape_string($mybb->input['cancustomtitle']),
		"canviewgames" => $db->escape_string($mybb->input['canviewgames']),
		"canplaygames" => $db->escape_string($mybb->input['canplaygames'])

4. IN THE SAME FILE FIND:
		"cancustomtitle" => $db->escape_string($mybb->input['cancustomtitle'])

REPLACE WITH:
		"cancustomtitle" => $db->escape_string($mybb->input['cancustomtitle']),
		"canviewgames" => $db->escape_string($mybb->input['canviewgames']),
		"canplaygames" => $db->escape_string($mybb->input['canplaygames'])

5. IN TE SAME FILE FIND:
	tablesubheader($lang->perms_misc);
	makeyesnocode($lang->can_view_mlist, "canviewmemberlist", "yes");
	makeyesnocode($lang->can_send_emails, "cansendemail", "yes");

AFTER ADD:
	$lang->set_language($mybb->settings['bblanguage'], "admin");
	$lang->load("games");
	tablesubheader($lang->perm_gamesection);
	makeyesnocode($lang->perm_canviewgames, "canviewgames", "yes");
	makeyesnocode($lang->perm_canplaygames, "canplaygames", "yes");

6. IN TE SAME FILE FIND:
	tablesubheader($lang->perms_misc);
	makeyesnocode($lang->can_view_mlist, "canviewmemberlist", $usergroup['canviewmemberlist']);
	makeyesnocode($lang->can_send_emails, "cansendemail", $usergroup['cansendemail']);

AFTER ADD:
	$lang->set_language($mybb->settings['bblanguage'], "admin");
	$lang->load("games");
	tablesubheader($lang->perm_gamesection);
	makeyesnocode($lang->perm_canviewgames, "canviewgames", $usergroup['canviewgames']);
	makeyesnocode($lang->perm_canplaygames, "canplaygames", $usergroup['canplaygames']);
