How do I use content notification and feedback tab?

In the announcement for typo 4 here:

Tow of the new features mentioned are:

  1. Email and/or Jabber notification of new content, including comments
    and
    trackbacks.

  2. Improved spam management. There’s a “Feedback” tab in the admin
    interface that lists all comments and trackbacks so they can be
    bulk-deleted. In addition, Typo can now use Akismet
    http://www.akismet.com/for spam filtering.

I have upgraded to typo 4.0. I don’t see a feedback table and when
someone
makes a comment, I don’t receive an email even when I have my email
address
filed in to the field “Email address to use in From: field when Typo
sends
mail:”.
