Everyone who have a concern for their privacy are warned not to communicate with People/businesses located in U.K, after 1/March/2009 ,using E-mail.
This is due to the fact the every E-mail's data (sent from or received in ) U.K will be recorded by the British government. It will be stored for a period of 1 year.
So if you have any concerns for your privacy,you are requested to use other means of communication,instead of using E-mail.e.g sms,phone call
If you think privacy is not a concern then you should read George Orwell's "Nineteen Eighty-Four".
