Some people don't like anti-aliasing--they think it makes text look fuzzy. Others prefer it. It's a matter of personal preference.
If you use a program like CorelXara or XaraWebster (which is included on your conference CD), all text is automatically anti-aliased, both on-screen and in your export, so what
you see is always exactly what you get. Very handy, with excellent results.
Colors: Make sure to use the browser-safe 216 colors for the solid areas of type--otherwise they will dither. The small anti-aliased areas will create non-browser safe colors, but these areas are so small that the dithering just smooths them further.
