Using Opera in fullscreen mode or normal mode, I can turn off the scroll bars. At 100% the forum fits nicely into the width of the screen without scrolling. If your eyesight is sharp, you can probably manage quite happily with that, but you will have to use the cursor keys or wheel mouse for scrolling.
However, if I turn the scroll bars on, I have to reduce the zoom to 90% to fit the forum in, much too small for me to read the 8 point Verdana text.
If I use my more usual 130% or 140% zoom, I have to struggle with the horizontal scroll bar too, which is rather irritating.
