2014 note: This site pushed the envelope back in 1999, but now it's pretty obsolete, and I've realized I may never be able to make it work on a smartphone unless I go back to college and major in database-driven dynamic web design. Which is unlikely. YMMV. I have not tested it on an iPad.
Check your browser preferences. This site is based on Javascript and (yes) frames. You'll need to have "Javascript Enabled" (Firefox/Chrome) or "Scripting Enabled"/"JScript Enabled" (Explorer). You don't need to enable "Java" however. Java is not Javascript.
If you find a bug, check the above list, then contact me and tell me as much detail as you can: what browser version you have, what operating system, and what triggered the error. REALLY helpful is if you tell me the error message you get, if any! Thanx. Happy browsing.
Cheers,
