I nearly forgot!
Grammar Captive is now accessible over a secure network. This means that you can now type https://www.grammarcaptive.com rather than http://www.grammarcaptive.com and still access the same website, but with secure access to every page — not just those for which your private information is requested.
It costs Grammar Captive just a little more, but I am just as afraid of government and thieves as you. By the way, the number of users using the https protocol has tripled since it was first introduced three months ago.
