No matter what I try it seems I cant get users to be emailed updates when users add bug notes. I have the following lines added to the config_inc.php file:

<?php
$g_hostname = 'localhost';
$g_db_type = 'mysql';
$g_database_name = 'pywork_mantis';
$g_db_username = 'pywork_dbuser';
$g_db_password = 'v6XuQest';

$g_notify_flags['new']['threshold_min'] = DEVELOPER;
$g_notify_flags['new']['threshold_max'] = ADMINISTRATOR;

$g_notify_flags['owner']['threshold_min'] = DEVELOPER;
$g_notify_flags['owner']['threshold_max'] = ADMINISTRATOR;

$g_notify_flags['reopened']['threshold_min'] = DEVELOPER;
$g_notify_flags['reopened']['threshold_max'] = ADMINISTRATOR;

$g_notify_flags['deleted']['threshold_min'] = DEVELOPER;
$g_notify_flags['deleted']['threshold_max'] = ADMINISTRATOR;

$g_notify_flags['updated']['threshold_min'] = DEVELOPER;
$g_notify_flags['updated']['threshold_max'] = ADMINISTRATOR;

$g_notify_flags['relation']['threshold_min'] = DEVELOPER;
$g_notify_flags['relation']['threshold_max'] = ADMINISTRATOR;

$g_notify_flags['bugnotes']['threshold_min'] = DEVELOPER;
$g_notify_flags['bugnotes']['threshold_max'] = ADMINISTRATOR;

$g_default_notify_flags = array('reporter'  => ON,
                                'handler'   => ON,
                                'monitor'   => ON,
                                'bugnotes'  => ON,
                                'threshold_min' => NOBODY,
                                'threshold_max' => NOBODY);

?>
