Before enabling the plugin, edit the plugin so the $mod_name and $mod_email variables contain the name and email address of the dedicated moderator. Example:
$mod_name = 'John Doe';
$mod_email = 'john@example.com';
If there are multiple dedicated moderators, use a generic name and a comma-separated list of email addresses:
$mod_name = 'Moderators';
$mod_email = 'moderator@example.com,anothermoderator@example.com';
