Excellent plugin. You can select if it notifies when a Page, Post and/or both is notified. You can select which of your users are notified (one, two, several, all or none), plus you can enter in additional emails addresses that notification emails to out to. The email notifications go out immediately and are well formatted, with both "BEFORE" and "AFTER text" included. Any additions/deletions of the text are highlighted in red and green highlithing. Fantastic plugin.
