There is a new free service at, http://alerts.dbtech.org/
It basically lets webmasters, and researchers register by entering thier email and the php script they use on thier website (such as phpBB etc)
It monitors new advisories and when it finds an advisory to be released for any of these scripts it sends the admins emails with links to information regarding the vulnerability.
You can use it for free at http://alerts.dbtech.org/
