Deadline for workshop and talk proposals is September 10th (if you should plan to give a talk), and a preliminary agenda is already available online. The registration process has also recently started (deadline is September 11th). See this post for the full announcement.

Update 2006-09-11: I have decided to register for the conference, so I'll be there! Anyone else?
