I want to assure everyone that we’re still here. Joe Adamson and I of course are both working our way through the end-of-semester trials of grading and exams, so that’s kept us pretty much pre-occupied. Moreover, the gods have determined that this is an especially good time for my home computer to crash. (It’s still not clear whether or not I’ve lost everything on it.) I am buying another today and hope to be up and more or less fully functioning very shortly.
