Got an uber-style sheet ready for NS6/IE6 based on the original wallpaper/3D effects. Even have BLOCKQUOTES correctly formatted in the beta (question; is fr_quote meant to replace BLOCKQUOTE when Forum 3 goes live?). Only have one problem; I either lose the fr_page_here/goto formatting in the beta (and had to change the color of the _here to red) or the A: formatting outside the text of the posts in Forum Classic.
Don't get me started with Nutscape 4.x. With style sheets (at least with my limited testing), images block text. Without style sheets, however, they don't.
