[support] Notification of New Content

[Fred Jones]

For 5.2, is there a way to notify the admins of any new content? My 
'Business Listings' site allows users to create accounts and then create 
a listing, which will be unpublished until the admins review it. I found 
this:

http://drupal.org/project/user_register_notify

which notifies on creation of user account.

Is there such a module which notifies on new content creation?

Seems trivial to write anyhow, if I knew the correct hook. :)

Thanks.
