I know it was one of the major reasons that Netscape Navigator 1 was such a huge success over IE1, but it's over. It's been done to death, and is hard on the eyes. The tag is <BLINK>:, is a container tag, and may contain other active HTML elements. Now that you know it - don't ever use it. And if you really must use it, at least don't tell anyone I taught it to you.
