There will be a major conference in Budapest later this year. The first OD World Summit is happening from 22-26 August 2010. Even better, SF will have a good role there - SFCT have been accepted as one of the official 'supporting organisations' alongside Appreciative Inquiry, Open Space, World Cafe, OD Network and many more.
You can find out more about the event at http://www.odworldsummit.org/ . The official closing date for proposals is 31 March, but SF people, having just found out about it, have an extension till 14 April. Several of us are already signed up, and I hope to do a couple of sessions with SF colleagues. Aoki is also bringing a Japanese case, and other proposals are in preparation.
I urge those of you interested in the world of OD to check it out, sign up (early bird also runs till 31 Mar) and offer a session too. Budapest, as those who were at the Summer University 2007 will know, is a beautiful city with lots of nice cafes and hot baths to relax in.
