Mrs. Duck, you got a few answers, but not all. I think MT is CH's reference to mousethief. HTML=Hyper-Text Markup Language. It began as a subset of SGML (standard generalized markup language), that's been around since at least the late 80's. Since it's all coded using plain ASCII text, all of our computers (Widoz, Apple, Unix) can read it if we have a program like Netscape, Internet Explorer or Opera that can read it. It's better than unmarked plain text because we get hyperlinks and content formatting like headings, bold or italics, that make reading easier.
