Hold the CTRL key down and press the plus ( + ) key next to the backspace key. Should increase your fonts. Assuming you are using FireFox. If that doesn't work, the universal Windows font resize is to hold the CTRL key down while rolling the scroll wheel on your mouse downward.
Thanks for your concern. I'm already aware of the Ctrl roll scroll
thingy and it's set at the largest IE font size available !!! ;-))
