If you're hungry for more online conferencing, here's another one. Not totally free of charge, but affordable with a fee of only ¤28 (euros). The topic looks very relevant to anyone interested in global affordances and consequences of communication opportunities.
Keywords: facilitators, globalization, open-space

Thanks for this link. I am hungry for on-line conferences:-)
I have also made some of my collegas in KHI aware of this, hoping that they will buy into the idea of open source, especially Moodle and see how we can use these tools as researchers.
