How are you notified of mssql patches?

Hi,
Might be a strange question, but I'm struggeling with it for a while..
Is there any website/newsletter/newsfeed, that just informs about new SQL
Server (2000 and 2005) patches?
With the Security Bulletin I don't get all fixes, just a few ones - at the
moment I always actively search for updates to prepare a sql server
maintenance and I would like to be notified about every patch regarding sql
server 2000 or sql server 2005.
Thanks and regards
Andreas
Hi Ben,
