Some of you might know about some CERN scientists starting protonmail after the whole wikileaks and Snowden info where a secure mail service(I forget the name) in the US was asked to open their files, the company wiped the servers and shut down instead. Being in Switzerland the hope is that snoopy and jealous nuclear armed superpowers will not violate the Swiss nutrality any more than they do to snoop the banking sector for tax cheats.
Anyways, I understand the API is open and even the free accounts are pretty great, but need more eyes on this. I would love to have this as an option for my N900 until we get the next great GNU-Linux flagship handheld.
