Our week-long online conference is now over. However, you are invited to read and comment on the conference papers located in the April 2012 archive. We had five papers this year, the same as the number of papers last year. Comments were interesting and provoked several good exchanges. The DPS site had nearly 900 visitors over the life of the conference, quite a spike over our usual weekly traffic of 400 or so visitors.

Thanks to our contributors, our commenters and all of the conference visitors.
