Both Netscape Navigator and MS Internet Explorer should be able to display all of the pages in this site beautifully, as long as you have a reasonably recent version (Navigator 4.5 or MSIE 4.0).
I do not test the pages on other browsers (like Opera), and I'm fairly certain that you'll have problems if you use a text browser (like Lynx). I just don't have time to support every browser ever built. Both Navigator and MSIE are free.
The preferred font for this site is Trebuchet MS Truetype font, available for free from Microsoft. Download it here. There are versions available for all versions of Windows, as well as Mac OS.
