Kat - I'm looking forward to hearing Cory's comments about the site, especially if he has any concerns about the readability of the text. We'd been playing around with font sizes and colors when I stumbled on the text size menu in Internet Explorer. I imagine Cory has been familiar with that solution for a long time now.
I'm most concerned about the contrast between the text and the background because Cory has mentioned its importance.
Charlie - thanks for another solution. I didn't know about the magnifier (but then I also run Windows ME and even Windows 98 on one or two boxes). 
I guess one more solution would be to go to somewhere like Start-->Settings-->Control Panel-->Display Properties (or whatever it's called these days) and fiddle with the resolution there. I'm guessing Cory has messed with Display Properties a time or two, too.
