I'll admit, I threw in a <FRAME> on my home node as a lark, since it only worked in Netscape anyway.
I'm surprised there isn't an inclusive list of tags, rather than some sort of exclude list. With so many problems with JavaScript, I'm still curious as to why that's even allowed.
I always thought the HTML-Scrubbing was done with code like in Why I like functional programming, because that's inclusive and works great. I use modifications of that code myself, because it's so great :). I wonder, too.
