[developers] changes to on-line MT and parsing demo code

[Dan Flickinger]

Hi Stephan -

I'm eager to try out the new version of the on-line demo, but when I
go to 
  http://erg.emmtee.net
I now get redirected to 
  http://erg.emmtee.net/logon 
and I get the following message:

  Bad Gateway
  The proxy server received an invalid response from an upstream server.

Can you advise?

Thanks,

 Dan
