Ross Mayfield donated a wiki for Internet Identity Workship 2005 and we've started to put it to use.
Kaliya has put together some hotel information for Berkeley.
We also have a page for Day One, which we'll fill out from the proposals we've received and invitations we've extended and Day Two, which is going to be run as a "structured open space." This page is a place for you to record things you'd like to see discussed or like to discuss yourself.
If you haven't registered, it's not too late. We're expecting a good crowd based on the registrations that have come in so far. We're going to cut off registration at 75 to ensure the group doesn't get too big for effective discussion.
