There are so many ways to describe this site, and all of them would leave something out. For me, it suffices to say that ET is a place with a high signal-to-noise ratio. The most universal implicit value is probably that Firefox is the preferred browser. Once you start posting, the rest of your questions will answer themselves.

Except perhaps HTML, of course. Which is where Firefox comes in (via someone's TribEXT, and a few other goodies out there for the downloading).

The fact is that what we're experiencing right now is a top-down disaster. -Paul Krugman
