I came across this site published by Bedford St. Martin's: "a journal for adjunct and graduate student teachers of writing published three times a year and edited by TAs, adjuncts, and assistant professors." For those of you who are career writing teachers, or supplement your living by being one part-time, this may be helpful. Categories include "informal discussions of everyday teaching issues," "an archived listserv on professional issues", "brief essays on various aspects of teaching and composition", and "stories and practical advice on job seeking and balancing work and life."
