I am now (month of Feb) participanting in a virtual conference on Knowledge Ecology Design and Knowledge Management. It is called the Knowledge Ecology Fair. It uses a conferencing system called "Caucus". You can check it out at <A HREF="http://www.co-i-l.com/kefair/">http://www.co-i-l.com/kefair/</A> .
About half of the activity at the site is happening in Open Space. Joe Paul
