This was a terribly uninformative article filled with various
inacuracies. Thanks for nothing punk.

>>
>> Can I encrypt email messages?
>>
>> Yes, but it’s tricky. Sender and receiver must use the same type of 
>> encryption. If you have encryption switched on, but the friend you’re 
>> emailing doesn’t have it, he or she won’t be able to read your message.
