We'll be sharing results of this analysis for the first time at the 2008
Natl Cohousing Conference (probably along with the John Abrams keynote on
Friday night - but possibly at the Sat morning Plenary).

After the Conference, we will most likely publish a high-level summary in
the Public portion of the Cohousing Website and the data itself in the new
Research Room of the new Members Area... Coho/US is also (formally)
announcing the new Members Area at the Conference. It will launch with just
a few rooms, but we'll be soliciting folks at the Conference to help us open
new Rooms.
