I mentioned this a while back but I think it is worth repeating. If you want a true KB service, it doesn't get much better than kbAlertz.com. In their own words:
kbAlertz.com is an e-mail notification system that scans the entire Microsoft Knowledge Base every night, and e-mails you when updates or additions are made to the technologies you subscribe to. Since we scan the entire knowledge base, we also have a pretty good search system for you to use on the left menu.
Subscribing is easy. Simply fill out your e-mail address and password below. Then, select the technologies that you're interested in. That's it. Now you'll be kept up to date when Microsoft publishes updates to your favorite technologies!
Have you checked it out. It's a great tool to have in your toolbox especially if your boss or one of your big customers is waiting for you to provide them guidance.
I'm luvin' the new Chris Botti Christmas CD called December. Check out 'the Christmas Song' or 'Ave Maria'.
