I don't want to go too wide with content on the forums, so was curious what resolution you browsed the forums at (typically). If you browse while playing MC, and make the window smaller because of it, try to estimate the horizontal resolution of the resized window. For instance, if you have a 1920x1200 resolution monitor, and you let the forum window take up half the screen, then your forum browsing resolution would be 960 pixels. If you only browse the forums with the whole screen, and you have a 1920x1200 resolution monitor, then your forum browsing resolution would be 1920 pixels. Make sense?
Mine tends to be about 900, which is about as small as it will allow before cutting off content in a scrollbar.
