That’s Weird!

My WP automatically changed the email settings of all the blogs i follow! I had set some blogs for instant email and some weekly email and some to be showed only in the reader, but now it has been changed to no notifications for all the blogs I follow! I wondered why my reader and email inbox was practically empty yesterday and today! Has this happened to any of you? What did you do to fix it?
Now I have to go and change the settings for 300 plus blogs that I follow manually!! Ugghh….usually I set up the notification when I start following somone! This is going to be hectic!!
