Max knows better than I do -- if he says no reg. is necessary, you can just show up to what interests you.
Mad props to Simmons for hosting such a great and open event. Some other people you may have met who will be there: Richard from WM-NYC, Katie Filbert from Wiki DC, Inc; and Phoebe Ayers, WMF trustee from Davis...
Also: the Archivist of the US is giving the opening keynote tomorrow. He really knows where his towel is... you should come to that if you can.
