If you value your privacy you should really endeavour to install PGP on your computer. This will enable you to send and receive encrypted emails to your family, friends and colleagues.
Personal privacy is of paramount importance in a democratic free society and we should always strive our utmost to protect it. Please contact, Digital Phenomena if you would like help and/or advice on setting it up. It's relatively easy and only needs to be done once.
This is an important issue because of the rapid proliferation of government surveillance in modern society. Using PGP will prevent ANYONE from being able to eavesdrop on your email communications.
Personal privacy is guarded under Article 12 of the United Nations Universal Declaration of Human Rights, which states that "No one shall be subjected to arbitrary interference with his privacy, family, home or correspondence..."
