Ok, I hope this is a coincidence, but I have had a yahoo account for years, and recently set up a Windows Live account using my yahoo email address. Yahoo and Windows Live recently started allowing the other service providers contacts to show up in their own IM apps (i.e. you can see yahoo contacts in MSN and vice versa). Well, I decided to close out the Windows Live account...and at the same time I cancel that account, I realize that I can no longer log in to my yahoo account. Not a happy camper. Maybe it's just a fluke...I don't know. Anyone hear of this happening elsewhere? I've sent in the standard "feedback form" to Yahoo, so I'll wait and see what happens. Just be forewarned...
