Dr. Jim Schepers has been my very able co-editor for several years. Last July, Jim stepped down to pursue other interests. I wish to record a very big thank you to him for his enthusiastic, accurate and detailed editing work. In his place, I welcome Dr. Paul Carter of Washington State University. Paul has already contributed significantly to PRAG as a referee over a number of years.
