I tried this example:

Visualisation example 3 (http://www.ami-communities.net/bscw/wiki.cgi/572?op=mindmap) this is the hypergraph soft applied to the collaboration@work community folder. ...

The tool asked me to log-in, although I was already logged in and then I received the the following error message from BSCW:

Error: No access
