Notification for new post from guest/member

I'm having trouble setting up the notification.
Whenever a guest post a new topic, only the administrator will get email/pop up message.
How can I set up for all moderators can get email notification when a guest/member post a new topic?

All moderators's permissions have set correctly but still didn't get a notification when a new topic got post in the forum.

Thank you~

Are they watching the forum and topics?  They will have to manually do this themselves in their profiles.
