I check daily on all my sites.

My home page is www.whateverdomain.com/wp-login.php x 8

If there is an update for lets say Akismet, in site #1, then 2-8 will need update.

I check out updates, then comments.

Is there a plugin that will e-mail me whenever there is an update for theme/plugin?

I don't mean those e-mails Matt sends whnever there is a new core upgrade.

This would be my own server/installation sending me an e-mail.
