Audit Trail is a plugin to keep track of what is going on inside your blog. It does this by recording certain actions (such as who logged in and when) and storing this information in the form of a log. Not only that but it records the full contents of posts (and pages) and allows you to restore a post to a previous version at any time.
To summarise:
<ul>
<li>Log of user actions inside your blog – useful for finding out who did what in a multi-user system</li>
<li>Extensible, allowing other plugins the ability to add and display items in the Audit Trail</li>
<li>Ability to track registered user page visits</li>
<li>Fully localized</li>
</ul>
Audit Trail is available in:
<ul>
<li>English</li>
<li>Estonian by Lembit Kivisik</li>
<li>Belorussian by Marcis G</li>
<li>Simplified Chinese by maoanyuan</li>
<li>German by Andreas Beraz</li>
<li>Japanese by Chestnut</li>

Each time a change is made to a post or page, those changes are emailed to the users and email addresses you specify.
Optionally, you can set what types of changes to email (post changes, page changes, attachment changes, or changes 
to any other ‘post type’ defined by any other plugin).
The changes are emailed as a unified diff. If the email client supports HTML emails, the diff will be colorized.

Email Post Changes

Emails you whenever a change to a post or page is made.
