Newsletter/Mailing list for security updates?

[Boxy]

An eBulletin is sent to all customers when a new or security release is made.

Alternatively, you can subscribe to the Announcements forum and you'll be sent notification when a new post/thread is added .

I probably dont check the announcements on this site as much as i should but wondered if there's a mailing list to signup to that will alert me instantly of any new security upgrades for the vbulletin software?
