How do I show users with Java disabled what they are missing?

You can place any content you want between the start and end <APPLET> tags. A Java-enabled browser will ignore this content. When Java is disabled, the browser will display the content (other then the <PARAM> tag). For instance, the following would be used to show a screendump for the user with Java disabled:

<APPLET code=Applet width=300 height=300>
If you had Java enabled, you would see an 
applet like the following:<br>

</APPLET>
