It's a link on the top of the home page. I bet you couldn't find your arse with both hands and a mirror.

non-free porn ?

Why not xxx.[country_code] for porn? No need to add an extra level just for that.
I like the idea of a separate porn tld, makes it easy both for those who want to find it, and those who want to avoid it.

Create three pages, one of which contains only links to the other two. Now "click" from one of the child pages to the other.

Use OpenPGP, there's the Enigmail plugin for Thunderbird, and a plugin for Outlook. Pretty sure there'll be something for Mac.
Certainly Enigmail can be configured to automatically fetch other peoples public keys.

Actually stabbing someone is very easy. That is why in close quarters, a knife is far more dangerous than a gun.

Do you think so?
Having done neither, I'd always thought that stabbing somebody would be more difficult - having to be "up close and personal", rather than at a distance and somewhat removed from the consequences of the act, as with a shooting.

Doesn't matter, unless they roll out a new CA cert every week.
It's the longevity, and security, of the CA cert that matters.
