A very Big Day for Avgi.... the sim where I am working.... 3500 people from a real life conference on educational opportunities in SL saw their Keynote speaker talk live from Avgi, after which they got the guided tour and a brief introduction to life in second life.
Johnny99 Gumshoe video'd the event and you can see clips here:
