Microsoft Password Checker

I'm sure there are many password validators or checkers. However, I happened to be reading a pretty good article from Microsoft on their research into passwords when I noticed a link to their page that will evaluate a string to see how strong it would be as a password. Their password checker is located here. While the policies and recommendations that are made should be known in the security field, the page is good for clients (and those needing education) as a way to gauge how good their passwords are.
