Forum .LRN Q&A: .LRN Demo Site

Galileo friendly provides the .LRN demo site at http://dotlrndemo.galileo.edu. It would be great to have it linked from http://demo.dotlrn.org as well (shorter to remember).

Additionally it would be good to have a couple of logins with demo classes on the site.

For German speaking users we did this already on http://demo.cognovis.de. It would be awesome if we had not only a German and English site but also Spanish and whatever language you like.

I had a look at this demo site and even tried to install the evaluation package on my .LRN 2.1.1 at AUBG. I did it from install software, but when I tried to add the evaluation applet I have got an error.

Where can I find your code?

Can you give me some advice?
