Hi

I'm trying to collarate and donate my voice to this project but I have a problem with the applet.

This is the entire stacktrace I get when loading your page

>JVMCFRE003 bad major version;

Should be fixed now.  Please retry submitting - if there is any problems, please let me know.

I recompiled the Java applet with Java 1.5 target (I had mistakenly compiled ithe latest release of the applet with Java 1.7).

thanks for letting us know!
