More info for those who need Java:
1) Direct link to download page for Sun Java for (for Windows XP, Me, NT, 2000, 98, or 95 and Internet Explorer):http://java.sun.com/getjava/download.html
This will add the current version of Java to Internet Explorer 5, 5.5, or 6. If you have XP it's currently the ONLY way to get Java.
2) Direct link to download page for Netscape 7.0 (which comes with Sun's Java as part of the "Full Installation" choice):http://channels.netscape.com/ns/browsers/download.jsp
(this one is for the online installer - just downloads a very small program, and then goes and gets just the pieces of the system you want)
(this one is to download the entire installation package first - easier if you have a fast connection or want to install on more than one computer)
3) Download page for Mozilla 1.0.http://www.mozilla.org/releases/stable.html
Mozilla is the open-source version of Netscape 7.0 with a few improvements (Pop-Up blocking for one). Officially it's "not for end-users", unofficially it's getting reviews as the best browser out there and better than Netscape 7 specifically because it doesn't have all the AOL commercialized add-ons. Either before or after you install Mozilla, you also need to install Sun Java (see 1 above). If you already have a recent Sun Java on your system, Mozilla should find it if you run Windows.
IE 5 or 5.5 from Microsoft with the "Microsoft Virtual Machine" (Microsoft's not-quite-Java) may work ok - but it may be the cause of some of the problems people have complained about from the chat room. Adding the Sun Java will help immensely. Plus if you then later download Netscape 7, you can leave out getting Java from them - it will use the Java you already installed, thus cutting about 15 Meg off the download.
