FeedBurner, the service that publishes the RSS and Email feed for Free Technology for Teachers, has been experiencing some problems this week. Some email subscribers may not have received updates yesterday. I have re-synched the feed so hopefully everything will be back to normal today. I apologize for any inconvenience.
On a related note, if you have signed up to receive email updates, but have not verified your email address please take a moment to do so. The verification email may have appeared in your junk or bulk email box.
