Change password notification

[gmagerr]

Hi all

I found this script on msdn and was wondering if someone could help me modify it. I need to query all of the accounts in AD (Users container for now) determine when the password was last set, when it will expire and send an email to users that they need to change their passwords when they are about to expire. I'd actually like to send them emails two weeks before, a week before then 2 days before. I don't really know where to start.

Thanks here's the code.
