when adding these lines to the config_inc.php file, the Permissions Report doesn't show the checkmarks where they should be.
(i.e. on the rows of 'Email on Reopened' and 'Email on Relationship changed' in the columns from Reporter to Administrator)

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

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

I'm not sure if it is just a matter of displaying it wrong or these settings actually do not work, as I have not yet tested these settings.
