This guy is not to be taken seriously.
I read his site. Then I saw that he mentions Hushmail as a great alternative.
That was THE WORST email I dealt with while being targeted. Its obviously a set up from the get to or its monitored due to its name. It closed me out, wouldnt let me read emails and even altered parts of emails. It was totally hacked in Tempe AZ.
Dont read this blog and dont use Hushmail.
