Is it possible you can install a skin that uses fixed widths for users who use browsers maximised on large monitors?
The only way I can correctly browse the forum these days is when I don't have my browser on full-screen, if I use a maximised window my posts look strange and I'm often having to put incorrect break space between my sentences because they look like paragraphs elsewhere e.g. this message box.
Of course this is broken with images or large letter spam breaks the page, if you can find one that forces the text to break or shrinks the images if it passes the width it'll be great.
